MM54HCT573 MM74HCT573 TRI-STATE Octal D-Type Latch MM54HCT574 MM74HCT574 TRI-STATE Octal D-Type Flip-Flop PRELIMINARY February 1990 MM54HCT573 MM74HCT573 TRI-STATE Octal D-Type Latch MM54HCT574 MM74HCT574 TRI-STATE Octal D-Type Flip-Flop General Description The MM54HCT573 MM74HCT573 octal D-type latches and MM54HCT574 MM74HCT574 Octal D-type flip flops advanced silicon-gate CMOS technology which provides the inherent benefits of low power consumption and wide power supply range but are LS-TTL input and output characteristic pin-out compatible The TRI-STATE outputs are capable of driving 15 LS-TTL loads All inputs are protected from damage due to static discharge by internal diodes to VCC and ground When the MM54HCT573 MM74HCT573 LATCH ENABLE input is high the Q outputs will follow the D inputs When the LATCH ENABLE goes low data at the D inputs will be retained at the outputs until LATCH ENABLE returns high again When a high logic level is applied to the OUTPUT CONTROL input all outputs go to a high impedance state regardless of what signals are present at the other inputs and the state of the storage elements The MM54HCT574 MM74HCT574 are positive edge triggered flip-flops Data at the D inputs meeting the setup and hold time requirements are transferred to the Q outputs on positive going transitions of the CLOCK (CK) input When a high logic level is applied to the OUTPUT CONTROL (OC) input all outputs go to a high impedance state regardless of what signals are present at the other inputs and the state of the storage elements MM54HCT MM74HCT devices are intended to interface between TTL and NMOS components and standard CMOS devices These parts are also plug in replacements for LSTTL devices and can be used to reduce power consumption in existing designs Features Y Y Y Y Y Y TTL input characteristic compatible Typical propagation delay 18 ns Low input current 1 mA maximum Low quiescent current 80 mA maximum Compatible with bus-oriented systems
