IN74HC573A

TECHNICAL DATA IN74HC573A Octal 3-State Noninverting Transparent Latch High-Performance Silicon-Gate CMOS N SUFFIX PLASTIC DIP The IN74HC573A 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 LE is high. When LE 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 µA High Noise Immunity Characteristic of CMOS Devices 20 1 20 1 DW SUFFIX SOIC ORDERING INFORMATION IN74HC573AN IN74HC573ADW Plastic DIP SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM 19 18 17 16 15 14 13 12 OE D0 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 V CC Q0 Q1 Q2 Q3 Q4 Q5 D0 D1 D2 DATA INPUTS D3 D4 D5 D6 D7 2 3 4 5 6 7 8 9 Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 NONINVERTING OUTPUTS D1 D2 D3 D4 D5 D6 D7 GND Q7 LE LE 11 OE 1 FUNCTION TABLE Inputs OE PIN 20=VCC PIN 10 = GND L L L H LE H H L X D H L X X Output Q H L no change Z w w a d . w e h s a t 4 t e u. m o c H= high level L = low level X = don’t care Z = high impedance 1 www.DataSheet4U.com Q6 IN74HC573A 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 (Refer...
