74HC393; 74HCT393 Dual 4-bit binary ripple counter Rev. 8 - 22 October 2021 Product data sheet 1. General description The 74HC393; 74HCT393 is a dual 4-stage binary ripple counter. Each counter Features a clock input (n CP), an overriding asynchronous master reset input (n MR) and 4 buffered parallel outputs (n Q0 to n Q3). The counter advances on the HIGH-to-LOW transition of n CP. A HIGH on n MR clears the counter stages and forces the outputs LOW, independent of the state of n CP. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2. Features and benefits - Wide supply voltage range from 2.0 V to 6.0 V - CMOS low power dissipation - High noise immunity - Latch-up performance exceeds 100 m A per JESD 78 Class II Level B - plies with JEDEC standards: - JESD8C (2.7 V to 3.6 V) - JESD7A (2.0 V to 6.0 V) - Input levels: - For 74HC393: CMOS level - For 74HCT393: TTL level - ESD protection: - HBM JESD22-A114F exceeds 2000 V - MM JESD22-A115-A exceeds 200 V. - Two 4-bit binary counters with individual clocks - Divide by any binary module up to 28 in one package - Two master resets to clear each 4-bit counter individually 3.
