DM74LS161A DM74LS163A Synchronous 4-Bit Binary Counters August 1986 Revised April 2000 DM74LS161A DM74LS163A Synchronous 4-Bit Binary Counters General Description These synchronous, presettable counters feature an internal carry look-ahead for application in high-speed counting designs. The DM74LS161A and DM74LS163A are 4-bit binary counters. The carry output is decoded by means of a NOR gate, thus preventing spikes during the normal counting mode of operation. Synchronous operation is prov
Fairchild Semiconductor - BCD DECADE COUNTERS / 4-BIT BINARY COUNTERS - Data
BCD DECADE COUNTERS, 4-BIT BINARY COUNTERS The LS160A , 161A , 162A , 163A are high-speed 4-bit synchronous counters. They are edge-triggered, synchronously presettable, and cascadable MSI building blocks for counting, memory addressing, frequency division and other applications. The LS160A and LS162A count modulo 10 (BCD). The LS161A and LS163A count modulo 16 (binary.) The LS160A and LS161A have an asynchronous Master Reset (Clear) input that overrides, and is independent of, the clock an
