74HC595; 74HCT595
8-bit serial-in, serial or parallel-out shift register with output
latches; 3-state
Rev. 11 — 10 September 2021
Product data sheet
1. General description
The 74HC595; 74HCT595 is an 8-bit serial-in/serial or parallel-out shift register with a storage
register and 3-state outputs. Both the shift and storage register have separate clocks. The device
features a serial input (DS) and a serial output (Q7S) to enable cascading and an asynchronous
reset MR input. A LOW on MR will reset the shift register. Data is shifted on the LOW-to-HIGH
transitions of the SHCP input. The data in the shift register is transferred to the storage register
on a LOW-to-HIGH 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. Data in the storage register
appears at the output whenever the output enable input (OE) is LOW. A HIGH on OE causes the
outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect the
state of the registers. Inputs include clamp diodes. This enables the use of current limiting resistors
to interface inputs to voltages in excess of VCC.

Typical values are measured at nominal supply voltage.
tpd is the same as tPHL and tPLH.
ten is the same as tPZL and tPZH.
tdis is the same as tPLZ and tPHZ.
CPD is used to determine the dynamic power dissipation (PD in μW).

PD = CPD × VCC × fi + Σ(CL × VCC × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
2
Σ(CL × VCC × fo) = sum of outputs;
CL = output load capacitance in pF;
VCC = supply voltage in V.
