description
These counters are fully programmable; they may
be preset to any number between 0 and 255. The
load-input circuitry allows parallel loading of the
cascaded counters. Because loading is
synchronous, selecting the load mode disables
the counter and causes the outputs to agree with
the data inputs after the next clock pulse.

These synchronous, presettable, 8-bit up/down
counters feature internal-carry look-ahead
circuitry for cascading in high-speed counting
applications. Synchronous operation is provided
by having all flip-flops clocked simultaneously so
that the outputs change coincidentally with each
other when so instructed by the count-enable
(ENP, ENT) inputs and internal gating. This mode
of operation eliminates the output counting spikes
normally associated with asynchronous (rippleclock) counters. A buffered clock (CLK) input
triggers the eight flip-flops on the rising (positivegoing) edge of the clock waveform.

NC – No internal connection
The carry look-ahead circuitry provides for cascading counters for n-bit synchronous applications without
additional gating. Two count-enable (ENP and ENT) inputs and a ripple-carry (RCO) output are instrumental
in accomplishing this function. Both ENP and ENT must be low to count. The direction of the count is determined
by the levels of the select (S0, S1) inputs as shown in the function table. ENT is fed forward to enable RCO. RCO
thus enabled produces a low-level pulse while the count is zero (all outputs low) counting down or 255 counting
up (all outputs high). This low-level overflow-carry pulse can be used to enable successive cascaded stages.
Transitions at ENP and ENT are allowed regardless of the level of CLK. All inputs are diode clamped to minimize
transmission-line effects, thereby simplifying system design.
These counters feature a fully independent clock circuit. With the exception of the asynchronous clear on the
SN74ALS867A and ′AS867, changes at S0 and S1 that modify the operating mode have no effect on the Q
outputs until clocking occurs. For the ′AS867 and ′AS869, any time ENP and/or ENT is taken high, RCO either
goes or remains high. For the SN74ALS867A and SN74ALS869, any time ENT is taken high, RCO either goes
or remains high. The function of the counter (whether enabled, disabled, loading, or counting) is dictated solely
by the conditions meeting the stable setup and hold times.

Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
C. When measuring propagation delay items of 3-state outputs, switch S1 is open.
D. All input pulses have the following characteristics: PRR ≤ 1 MHz, tr = tf = 2 ns, duty cycle = 50%.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)

performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should
provide adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask
work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services

Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service
voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business
practice. TI is not responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would
reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement
specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications
of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related
requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any
applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its
representatives against any damages arising out of the use of TI products in such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is
solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in
connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products
are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any
non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
