SL74HC597 8-Bit Serial or Parallel-Input/ Serial-Output Shift Register with Input Latch High-Performance Silicon-Gate CMOS The SL74HC597 is identical in pinout to the LS/ALS597. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This device consists of an 8 -bit input latch which feeds parallel data to an 8-bit shift register. Data can also be loaded serially (see Function Table). • 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 SL74HC597N Plastic SL74HC597D SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 16 =VCC PIN 8 = GND SLS System Logic Semiconductor SL74HC597 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 ±25 ±50 750 500 -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 and 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.
