74HC597; 74HCT597

8-bit shift register with input flip-flops

The 74HC597; 74HCT597 is an 8-bit shift register with input flip-flops. It consists of an 8-bit storage register feeding a parallel-in, serial-out 8-bit shift register. Both the storage register and the shift register have positive edge-triggered clocks. The shift register also has direct load (from storage) and clear inputs. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Features and benefits

  • Wide supply voltage range from 2.0 V to 6.0 V
  • CMOS low power dissipation
  • High noise immunity
  • Input levels:
    • For 74HC597: CMOS level
    • For 74HCT597: TTL level
  • 8-bit parallel storage register inputs
  • Shift register has direct overriding load and clear
  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
  • Complies with JEDEC standards
    • JESD8C (2.7 V to 3.6 V)
    • JESD7A (2.0 V to 6.0 V)
  • ESD protection:
    • HBM EIA/JESD22-A114F exceeds 2000 V
    • MM EIA/JESD22-A115-A exceeds 200 V
  • Multiple package options
  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C
