8-bit serial-in/serial or parallel-out shift register with output latches; 3-state
Philips Semiconductors Product specification
8-bit serial-in/serial or parallel-out shift
register with output latches; 3-state 74HC/HCT595
FEATURES 8-bit serial input 8-bit serial or parallel output Storage register with 3-state outputs Shift register with direct clear 100 MHz (typ) shift out frequency Output capability: parallel outputs; bus driver serial output; standard ICC category: MSI.
APPLICATIONS Serial-to-parallel data conversion Remote control holding register.
DESCRIPTIONThe 74HC/HCT595 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 “595” is an 8-stage serial shift register with a storage
register and 3-state outputs. The shift register and storage
register have separate clocks.
Data is shifted on the positive-going transitions of the
SHCP input. The data in each register is transferred to the
storage register on a positive-going transition of the STCP
input. If both clocks are connected together, the shift
register will always be one clock pulse ahead of the
storage register.
The shift register has a serial input (DS) and a serial
standard output (Q7’) for cascading. It is also provided with
asynchronous reset (active LOW) for all 8 shift register
stages. The storage register has 8 parallel 3-state bus
driver outputs. Data in the storage register appears at the
output whenever the output enable input (OE) is LOW.
QUICK REFERENCE DATAGND= 0 V; Tamb =25 °C; tr =tf= 6 ns.
Notes CPD is used to determine the dynamic power dissipation (PD in μW): =CPD× VCC2×fi +∑ (CL× VCC2× fo) where:= input frequency in MHz= output frequency in MHz
∑(CL× VCC2×fo)= sum of outputs= output load capacitance inpF
VCC= supply voltage inV For HC the condition is VI= GND to VCC; for HCT the condition is VI= GND to VCC− 1.5V.

Note to HCT typesThe value of additional quiescent supply current (ΔICC) for a unit load of 1 is given in the family specifications.
To determine ΔICC per input, multiply this value by the unit load coefficient shown in the table below.
