SL74HCT574

SL74HCT574 Octal 3-State Noninverting D Flip-Flop High-Performance Silicon-Gate CMOS The SL74HCT574 is identical in pinout to the LS/ALS574. This device may be used as a level converter for interfacing TTL or NMOS outputs to High-Speed CMOS inputs. Data meeting the setup 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, all device 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 SL74HCT574N Plastic SL74HCT574D SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE PIN 20=VCC PIN 10 = GND Output Enable L L L H L,H, X Inputs Clock D H L X X Output Q H L no change Z X = don’t care Z = high impedance System Logic Semiconductor SLS SL74HCT574 MAXIMUM RATINGS * Symbol VCC VIN VOUT IIN IOUT ICC PD T stg 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 mA mA mA mW °C °C Maximum Ratings are those values beyond which damage to the device may occur.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN a nd VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V ). CC Unused outputs must be left open.
