SN5474,SN54LS74A,SN54S74 SN7474.SN74LS74A,SN74S74 DUAL D-TYPE POSITIVE-EDGE-TRIGGERED FLIP-FLOPS WITH PRESET AND CLEAR
This document is a datasheet for the Texas Instruments SN5474, SN54LS74A, SN54S74, SN7474, SN74LS74A, and SN74S74 series. These devices contain two independent D-type positive-edge-triggered flip-flops with preset and clear inputs. The data is transferred to the outputs on the positive-going edge of the clock pulse when the preset and clear inputs are inactive (high).
