SL74HC373 Datasheet | System Logic Semiconductor

Octal 3-State Noninverting Transparent Latch High-Performance Silicon-Gate CMOS The SL74HC373 is identical in pinout to the LS/ALS373. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible 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 bees 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 high-impedance 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 SL74HC373N Plastic SL74HC373D SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs PIN 20=VCC PIN 10 = GND Output Enable L L L H Latch Enable H H L X D H L X X Output Q H L No Change Z X = Don’t Care Z = High Impedance System Logic Semiconductor 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 Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) Value -0.5 to +7.0 -1.5 to VCC +1.5 -0.5 to VCC +0.5 ±20 ±35 ±75 750 500 -65 to +150 260 Unit V V V m A m A m A m W °C °C Maximum Ratings are those values beyond which damage to the device may occur.
