Dual synchronous BCD counter

GENERAL DESCRIPTION The 74HC/HCT4518 are high-speed Si-gate CMOS devices and are pin compatible with the “4518” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A. FEATURES • Output capability: standard • ICC category: MSI APPLICATIONS • Multis

Dual BCD Use Converters/Dual Binary Up Converters

Description The HD74HC4518 dual BCD counter and the HD74HC4520 dual binary counter consist of two identical, independent, internally synchronous 4-stage counters. The counter stages are type D flip-flops, with interchangeable Clock and Enable lines for incrementing on either the positive-going

HC4518 DUAL DECADE COUNTER HC4520 DUAL 4 BIT BINARY COUNTER

DESCRIPTION The M54/74HC4518/4520 are high speed CMOS DUAL 4 BIT BINARY COUNTERS fabricated in silicon gate C2MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption. .HIGH SPEED fMAX= 55 MHz (TYP.) at VCC=5V .LOW POWER DISSI
