CD54/74HC161, CD54/74HCT161, CD54/74HC163, CD54/74HCT163 Data sheet acquired from Harris Semiconductor SCHS154D High-Speed CMOS Logic Presettable Counters February 1998 - Revised October 2003 Features Two count enables, PE and TE, in each counter are provided for n-bit cascading. In all counters reset action occurs regardless of the level of the SPE, PE and TE inputs (and the clock input, CP, in the ’HC161 and ’HCT161 types). • ’HC161, ’HCT161 4-Bit Binary Counter, Asynchronous Reset • ’HC163, ’HCT163 4-Bit Binary Counter, Synchronous Reset If a decade counter is preset to an illegal state or assumes an illegal state when power is applied, it will return to the normal sequence in one count as shown in state diagram. • Synchronous Counting and Loading • Two Count Enable Inputs for n-Bit Cascading The look-ahead carry feature simplifies serial cascading of the counters. Both count enable inputs (PE and TE) must be high to count. The TE input is gated with the Q outputs of all four stages so that at the maximum count the terminal count (TC) output goes high for one clock period. This TC pulse is used to enable the next cascaded stage. • Look-Ahead Carry for High-Speed Counting • Fanout (Over Temperature Range) - Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads - Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads • Wide Operating Temperature Range . . . -55oC to 125oC • Balanced Propagation Delay and Transition Times Ordering Information • Significant Power Reduction Compared to LSTTL Logic ICs • HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V PART NUMBER TEMP.

The ’HC161 and ’HCT161 are asynchronous reset decade and binary counters, respectively; the ’HC163 and ’HCT163 devices are decade and binary counters, respectively, that are reset synchronously with the clock. Counting and parallel presetting are both accomplished synchronously with the negative-to-positive transition of the clock.

In the ’HC163 and ’HCT163 counters (synchronous reset types), the requirements for setup and hold time with respect to the clock must be met. NOTE: When ordering, use the entire part number. The suffix 96 denotes tape and reel. The suffix T denotes a small-quantity reel of 250. CAUTION: These devices are sensitive to electrostatic discharge. Users should follow proper IC Handling Procedures.

NOTES: 1. The TC output is High when TE is High and the counter is at Terminal Count (HHHH for HC/HCT161 and ’HC/HCT163). 2. The High-to-Low transition of PE or TE on the ’HC/HCT161 and the ’HC/HCT163 should only occur while CP is HIGH for conventional operation. 3. The Low-to-High transition of SPE on the ’HC/HCT161 and SPE or MR on the ’HC/HCT163 should only occur while CP is HIGH for conventional operation. 3 CD54/74HC161, CD54/74HCT161, CD54/74HC163, CD54/74HCT163 Absolute Maximum Ratings Thermal Information DC Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . -0.5V to 7V DC Input Diode Current, IIK For VI < -0.5V or VI > VCC + 0.5V . . . . . . . . . . . . . . . . . . . . . .±20mA DC Output Diode Current, IOK For VO < -0.5V or VO > VCC + 0.5V . . . . . . . . . . . . . . . . . . . .±20mA DC Drain Current, per Output, IO For -0.5V < VO < VCC + 0.5V. . . . . . . . . . . . . . . . . . . . . . . . . .±25mA DC Output Source or Sink Current per Output Pin, IO For VO > -0.5V or VO < VCC + 0.5V . . . . . . . . . . . . . . . . . . . .±25mA DC VCC or Ground Current, ICC . . . . . . . . . . . . . . . . . . . . . . . . .±50mA Thermal Resistance (Typical, Note 4) θJA (oC/W) E (PDIP) Package . . . . . . . . . . . . . . . . . . . . . . . . . . 67 M (SOIC) Package. . . . . . . . . . . . . . . . . . . . . . . . . . 73 Maximum Junction Temperature . . . . . . . . . . . . . . . . . . . . . . . 150oC Maximum Storage Temperature Range . . . . . . . . . .-65oC to 150oC Maximum Lead Temperature (Soldering 10s) . . . . . . . . . . . . . 300oC (SOIC - Lead Tips Only) Operating Conditions Temperature Range, TA . . . . . . . . . . . . . . . . . . . . . . -55oC to 125oC Supply Voltage Range, VCC HC Types . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .2V to 6V HCT Types . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .4.5V to 5.5V DC Input or Output Voltage, VI, VO . . . . . . . . . . . . . . . . . 0V to VCC Input Rise and Fall Time 2V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1000ns (Max) 4.5V. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 500ns (Max) 6V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 400ns (Max) CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device.

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. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. Addendum-Page 2 PACKAGE OPTION ADDENDUM www.ti.com 9-Oct-2007 OBSOLETE: TI has discontinued the production of the device. (2) 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) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
