Product specication
8-bit shift register with input ip-ops
74HC/HCT597
FEATURES
8-bit parallel storage register inputs
Shift register has direct overriding load and clear
Output capability: standard
ICC category: MSI
GENERAL DESCRIPTION
The 74HC/HCT597 are high-speed Si-gate CMOS devices
and are pin compatible with low power Schottky TTL
(LSTTL). They are specified in compliance with JEDEC
standard no. 7A.
The 74HC/HCT597 consist each 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.
QUICK REFERENCE DATA
GND = 0 V; Tamb =25 °C; tr =tf = 6 ns
Notes
1. CPD is used to determine the dynamic power dissipation (PD in W):
PD =CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where:
fi = input frequency in MHz
fo = output frequency in MHz
∑ (CL × VCC2 × fo) = sum of outputs
CL = output load capacitance in pF
VCC = supply voltage in V
2. For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC 1.5 V
