MC74HC161A,
MC74HC163A
Presettable Counters
High−Performance Silicon−Gate CMOS
The MC74HC161A and HC163A are identical in pinout to the
LS161 and LS163. The device inputs are compatible with standard
CMOS outputs; with pullup resistors, they are compatible with
LSTTL outputs.
The HC161A and HC163A are programmable 4−bit binary counters
with asynchronous and synchronous reset, respectively.

MC74HC161A, MC74HC163A
FUNCTION DESCRIPTION
CONTROL FUNCTIONS
The HC161A/163A are programmable 4−bit synchronous
counters that feature parallel Load, synchronous or
asynchronous Reset, a Carry Output for cascading, and
count−enable controls.
The HC161A and HC163A are binary counters with
asynchronous Reset and synchronous Reset, respectively.
Resetting
A low level on the Reset pin (Pin 1) resets the internal
flip−flops and sets the outputs (Q0 through Q3) to a low
level. The HC161A resets asynchronously, and the HC163A
resets with the rising edge of the Clock input (synchronous
reset).
INPUTS
Loading
Clock (Pin 2)
With the rising edge of the Clock, a low level on Load
(Pin 9) loads the data from the Preset Data input pins (P0,
P1, P2, P3) into the internal flip−flops and onto the output
pins, Q0 through Q3. The count function is disabled as long
as Load is low.
The internal flip−flops toggle and the output count
advances with the rising edge of the Clock input. In addition,
control functions, such as resetting and loading, occur with
the rising edge of the Clock input.
Preset Data Inputs P0, P1, P2, P3 (Pins 3, 4, 5, 6)
These are the data inputs for programmable counting.
Data on these pins may be synchronously loaded into the
internal flip−flops and appear at the counter outputs.
P0 (Pin 3) is the least−significant bit and P3 (Pin 6) is the
most−significant bit.
Count Enable/Disable
OUTPUTS
The count is either enabled or disabled by the control
inputs according to Table 1. In general, Enable P is a
count−enable control: Enable T is both a count−enable and
a Ripple−Carry Output control.
These devices have two count−enable control pins:
Enable P (Pin 7) and Enable T (Pin 10). The devices count
when these two pins and the Load pin are high. The logic
equation is:
Count Enable = Enable P • Enable T • Load
Q0, Q1, Q2, Q3 (Pins 14, 13, 12, 11)
These are the counter outputs. Q0 (Pin 14) is the
least−significant bit and Q3 (Pin 11) is the most−significant
bit.
Table 1. Count Enable/Disable
Control Inputs
Ripple Carry Out (Pin 15)
Result at Outputs
When the counter is in its maximum state, 1111, this
output goes high, providing an external look−ahead carry
pulse that may be used to enable successive cascaded
counters. Ripple Carry Out remains high only during the
maximum count state. The logic equation for this output is:

The flip−flops shown in the circuit diagrams are Toggle−Enable flip−flops. A Toggle−
Enable flip−flop is a combination of a D flip−flop and a T flip−flop. When loading data from
Preset inputs P0, P1, P2, and P3, the Load signal is used to disable the Toggle input (Tn) of
the flip−flop. The logic level at the Pn input is then clocked to the Q output of the flip−flop
on the next rising edge of the clock.
A logic zero on the Reset device input forces the internal clock (C) high and resets the Q
output of the flip−flop low.

The flip−flops shown in the circuit diagrams are Toggle−Enable flip−flops. A Toggle−
Enable flip−flop is a combination of a D flip−flop and a T flip−flop. When loading data from
Preset inputs P0, P1, P2, and P3, the Load signal is used to disable the Toggle input (Tn) of
the flip−flop. The logic level at the Pn input is then clocked to the Q output of the flip−flop
on the next rising edge of the clock.
A logic zero on the Reset device input forces the internal clock (C) high and resets the Q
output of the flip−flop low.

NOTE: When used in these cascaded configurations the clock fmax guaranteed limits may not apply. Actual performance will
depend on number of stages. This limitation is due to set up times between Enable (Port) and Clock.

The HC163A facilitates designing counters of any modulus with minimal external logic. The output is glitch−free due to
the synchronous Reset.
