Overview

TC74AC161,163P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC161P, TC74AC161F, TC74AC161FT TC74AC163P, TC74AC163F, TC74AC163FT Synchronous Presettable 4-Bit Binary Counter TC74AC161P/F/FT Asynchronous Clear TC74AC163P/F/FT Synchronous Clear TC74AC161P, TC74AC163P The TC74AC161 and 163 are advanced high speed CMOS SYNCHRONOUS PRESETTABLE COUNTERs fabricated with silicon gate and double-layer metal wiring C2MOS technology.

They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.

The CK input is active on the rising edge.
