Overview
CD40160BMS, CD40161BMS, CD40162BMS, CD40163BMS December 1992 File Number 3358 CMOS Synchronous Programmable 4-Bit Counters CD40160BMS, CD40161BMS, CD40162BMS and CD40163BMS are 4-bit synchronous programmable counters.
The CLEAR function of the CD40162BMS and CD40163BMS is synchronous and a low level at the CLEAR 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 CLEAR 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.
