CD40160BMS,CD40161BMS,CD40162BMSand
CD40163BMSare4-bitsynchronousprogrammable
counters. The CLEAR function of the CD40162BMS and
CD40163BMS is synchronous and a low level at the
input sets all four outputs low on the next positive CLOCK
edge. The CLEAR function of the CD40160BMS and
CD40161BMS is asychronous and a low level at the
input sets all four outputs low regardless of the state of the
CLOCK,
LOAD, or ENABLE inputs. A low level at the LOAD
input disables the counter and causes the output to agree
with the setup data after the next CLOCK pulse regardless of
the conditions of the ENABLE inputs.
The carry look-ahead circuitry provides for cascading counters
for n-bit synchronous applications without additional gating.
Instrumental in accomplishing this function are two count-enable
inputs and a carry output (COUT). Counting is enabled when
both PE and TE inputs are high. The TE input is fed forward to
enable COUT. This enabled output produces a positive output
pulses with a duration approximately equal to the positive portion
of the Q1 output. This positive overflow carry pulse can be used
to enable successive cascaded stages. Logic transitions at the
PE or TE inputs may occur when the clock is either high or low.
The CD40160BMS through CD40163BMS types are functionally
equivalent to and pin-compatible with the TTL counter series
74LS160 through 74LS163 respectively.

NOTES:
1. All voltages referenced to device GND.
2. The parameters listed on Table 3 are controlled via design or process and are not directly tested. These parameters are characterized on initial
design release and upon design changes which would affect these characteristics.
3. CL = 50pF, RL = 200K, Input TR, TF < 20ns.
4. If more than one unit is cascaded, TRCL should be made less than or equal to the sumof the transition time and the fixed propagation delay of
the output of the driving stage for the estimated capacitive load.
