SYMMETRICAL OUTPUT IMPEDANCE: |I OH | = I OL = 4mA (MIN) BALANCED PROPAGATION DELAYS: t PLH ≅ t PHL WIDE OPERATING VOLTAGE RANGE: V CC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 4518 DIP SOP TSSOP ORDER CODES PACKAGE DIP SOP TSSOP TUBE M74HC4518B1R M74HC4518M1R T&R M74HC4518RM13TR M74HC4518TTR DESCRIPTION The M74HC4518 is an high speed CMOS DUAL BINARY COUNTER fabricated with silicon gate C 2 MOS technology. It consist of two identical internally synchronous 4-stage counters. The counter stages are D-TYPE flip-flops having interchangeable CLOCK and ENABLE inputs for incrementing on either the positive-going or negative-going transition. For single-unit operation the ENABLE input is maintained "high" and the counter advances on
