Product details. Documentation. Support. Ordering. 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 mA per JESD 78 Class II Level B. Complies with JEDEC standards: JESD8C (2.7 V to 3.6 V) JESD7A (2.0 V to 6.0 V) Input levels:
Description. The CD74HC4518 is a dual BCD up-counter. The ’HC4520 and CD74HCT4520 are dual binary up-counters. Each device consists of two independent internally synchronous 4-stage counters. The counter stages are D-type flip-flops. input of the latter is held low. Ordering Information. NOTE: When ordering, use the entire part number.
The 74HC/HCT4520 are dual 4-bit internally synchronous binary counters with an active HIGH clock input (nCP0) and an active LOW clock input (nCP1), buffered outputs from all four bit positions (nQ0 to nQ3) and an active HIGH overriding asynchronous master reset input (nMR).

1. General description. The 74HC4520; 74 HCT4520 are dual 4-b it intern ally synchronous binary counters with. two clock inputs (nCP0 an d nCP 1). They have buffered outputs from all 4 bit positions. (nQ0 to nQ3) and an asynchron ous master reset input (nMR). The counte r advances on. the LOW-to-HIGH transition of nCP0 when nCP 1 is HIGH.
