IN74HCT374A

TECHNICAL DATA IN74HCT374A Octal 3-State Noninverting D Flip-Flop High-Performance Silicon-Gate CMOS The IN74HCT374A is identical in pinout to the LS/ALS374. The IN74HCT374A may be used as a level converter for interfacing TTL or NMOS outputs to High-Speed CMOS inputs. Data meeting the setup and hold time is clocked to the outputs with the rising edge of the Clock. The Output Enable input does not affect the states of the flip-flops, but when Output Enable is high, the outputs are forced to the high-impedance state; thus, data may be stored even when the outputs are not enabled. TTL/NMOS-Compatible Input Levels Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 4.5 to 5.5 V Low Input Current: 1.0 µA ORDERING INFORMATION IN74HCT374AN Plastic IN74HCT374ADW SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE PIN 20=VCC PIN 10 = GND Inputs Output Enable L L L H L,H, X Clock D H L X X Output Q H L no change Z w w w .d e e h s a t a . u t4 m o c X = don’t care Z = high impedance 1 www.DataSheet4U.com IN74HCT374A 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 ...
