MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC74HC125A Quad 3-State MC74HC126A Noninverting Buffers High–Performance Silicon–Gate CMOS The MC74HC125A and MC74HC126A are identical in pinout to the LS125 N SUFFIX and LS126. The device inputs are compatible with standard CMOS outputs; PLASTIC PACKAGE 14 with pullup resistors, they are compatible with LSTTL outputs. CASE 646–06 The HC125A and HC126A noninverting buffers are designed to be used 1 with 3–state memory address drivers, clock drivers, and other bus–oriented systems. The devices have four separate output enables that are active–low D SUFFIX (HC125A) or active–high (HC126A). 14 SOIC PACKAGE • Output Drive Capability: 15 LSTTL Loads CASE 751A–03 1 • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Volt
