Overview

CD40160BM BC Decade Counter with Asynchronous CD40162BM BC Synchronous Clear CD40161BM BC Binary Counter with Asynchronous CD40163BM BC Synchronous Clear March 1988 CD40160BM CD40160BC Decade Counter with Asynchronous Clear CD40161BM CD40161BC Binary Counter with Asynchronous Clear CD40162BM CD40162BC Decade Counter with Synchronous Clear CD40163BM CD40163BC Binary Counter with Synchronous Clear General Description These (synchronous presettable up) counters are monolithic complementary MOS (CMOS) integrated circuits constructed with N- and P-channel enhancement mode transistors They feature an internal carry look-ahead for fast counting schemes and for cascading packages without additional gating A low level at the load input disables counting and causes the outputs to agree with the data input after the next positive clock edge The clear function for the CD40162B and CD40163B is synchronous and a low level at the clear input sets all four outputs low after the next positive clock edge The clear function for the CD40160B and CD40161B is asynchronous and a low level at the clear input sets all four outputs low regardless of the state of the clock Counting is enabled when both count enable inputs are high Input T is fed forward to also enable the carry out The carry output is a positive pulse with a duration approximately equal to the positive portion of QA and can be used to enable successive cascaded stages Logic transitions at the enable P or T inputs can occur when the clock is high or low Features Y Y Y Y Y Y Y Y Y Wide supply voltage range 3 0V to 15V High noise immunity 0 45 VDD (typ ) Low power TTL fan out of 2 driving 74L compatibility or 1 driving 74LS Internal look-ahead for fast counting schemes Carry output for N-bit cascading Load control line Synchronously programmable Equivalent to MC14160B MC14161B MC14162B MC14163B Equivalent to MM74C160 MM74C161 MM74C162 MM74C163 Connection Diagram Dual-In-Line Package Order Number CD40160B CD40161B CD40162...
