IN74HC373A

TECHNICAL DATA IN74HC373A Octal 3-State Noninverting Transparent Latch High-Performance Silicon-Gate CMOS The IN74HC373A is identical in pinout to the LS/ALS373. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. These latches appear transparent to data (i.e., the outputs change asynchronously) when Latch Enable is high. When Latch Enable goes low, data meeting the setup and hold time becomes latched. The Output Enable input does not affect the state of the latches, but when Output Enable is high, all device outputs are forced to the highimpedance state. Thus, data may be latched even when the outputs are not enabled. Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 µA High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION IN74HC373AN Plastic IN74HC373ADW SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Output D H L X X Q H L No Change Z w w w .d h s a t a ee . u t4 m o c PIN 20=VCC PIN 10 = GND Output Enable L L L H Latch Enable H H L X X = Don’t Care Z = High Impedance 1 www.DataSheet4U.com IN74HC373A MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg TL * Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Current, per Pin DC Supply Cu...
