The 74HC74 is identical in pinout to the LS74. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This device consists of two D flip−flops with individual Set, Reset, and Clock inputs. Information at a D−input is transferred

Dual D-type flip-flop with set and reset; positive-edge trigger

GENERAL DESCRIPTION The 74HC/HCT74 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. FEATURES • Output capability: standard • ICC category: flip-flops

Dual D-type flip-flop with set and reset; positive edge-trigger

1. General description The 74HC74 and 74HCT74 are dual positive edge triggered D-type flip-flop. They have individual data (nD), clock (nCP), set (nSD) and reset (nRD) inputs, and complementary nQ and nQ outputs. Data at the nD-input, that meets the set-up and hold time requirements on the LOW-
