8-bit shift register with output register
Product specification
74HC/HCT594
FEATURES
Synchronous serial input and output
8-bit parallel output
Shift and storage register have independent direct clear
and clocks
100 MHz (typ.)
Output capability:
– parallel outputs: bus driver
– serial outputs: standard
ICC category: MSI
APPLICATIONS
Serial-to parallel data conversion
Remote control holding register
DESCRIPTION
The 74HC/HCT594 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/HCT594 contain an 8-bit, non-inverting,
serial-in, parallel-out shift register that feeds an 8-bit
D-type storage register. Separate clocks and direct
overriding clears are provided on both the shift and storage
registers. A serial output (Q7’) is provided for cascading
purposes.
Both the shift and storage register clocks are positive-edge
triggered. If the user wishes to connect both clocks
together, the shift register will always be one count pulse
ahead of the storage register.

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi + (CL × VCC2 × fo), where:
fi = input frequency in MHz; fo = output frequency in MHz;
(CL × VCC2 × fo) = sum of the 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.
