SL74HC573 Octal 3-State Noninverting Transparent Latch High-Performance Silicon-Gate CMOS The SL74HC573 is identical in pinout to the LS/ALS573. 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. Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 A High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION SL74HC573N Plastic SL74HC573D SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM PIN 20=VCC PIN 10 = GND FUNCTION TABLE Inputs 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 SLS System Logic Semiconductor SL74HC573 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……
