MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC74HCT273A Octal D Flip-Flop with Common Clock and Reset with LSTTL Compatible Inputs N SUFFIX PLASTIC PACKAGE High–Performance Silicon–Gate CMOS 20 CASE 738–03 1 The MC74HCT273A may be used as a level converter for interfacing TTL or NMOS outputs to High–Speed CMOS inputs. DW SUFFIX The HCT273A is identical in pinout to the LS273. 20 SOIC PACKAGE 1 This device consists of eight D flip–flops with common Clock and Reset CASE 751D–04 inputs. Each flip–flop is loaded with a low–to–high transition of the Clock input. Reset is asynchronous and active low. ORDERING INFORMATION • Output Drive Capability: 10 LSTTL Loads MC74HCTXXXAN Plastic • TTL/NMOS Compatible Input Levels MC74HCTXXXADW SOIC • Outputs Directly Interface to CMOS,
