74HC393 Datasheet (PDF) - NXP Semiconductors
The 74HC/HCT393 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT393 are 4-bit binary ripple counters with separate clocks (1CP and 2 CP) and master reset (1MR and 2MR) inputs to each counter.
The ’HC393 and ’HCT393 are 4-stage ripple-carry binary counters. All counter stages are primary-operative flip-flops. The state of the stage advances one count on the negative transition of …
