SN74LS161D中文资料安森美半导体数据手册PDF规格书

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.)

• Synchronous Counting and Loading

• Two Count Enable Inputs for High Speed Synchronous Expansion

• Terminal Count Fully Decoded

• Edge-Triggered Operation

• Typical Count Rate of 35 MHz

• ESD > 3500 Volts
