74LVC8T595
Dual supply 8-bit serial-in/serial-out or parallel-out shift
register; 3-state
Rev. 1 — 9 May 2017
Product data sheet
1 General description
The 74LVC8T595 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.
Data is shifted on the positive-going transitions of the SHCP input. The data in the shift
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 is always one clock pulse
ahead of the storage register.
VCC(A) and VCC(B) can be supplied at any voltage between 1.1 V and 5.5 V making the
device suitable for translating between any of the voltage nodes (1.2 V, 1.5 V, 1.8 V,
2.5 V, 3.3 V and 5.0 V). Pins MR, SHCP, STCP, OE, DS and Q7S are referenced to
VCC(A) and pins Qn are referenced to VCC(B).
The device is fully specified for partial power-down applications using IOFF. The IOFF
circuitry disables the output, preventing any damaging backflow current through the
device when it is powered down. In suspend mode when VCC(A) is at GND level, the Qn
outputs are in the high-impedance OFF-state.
2 Features and benefits
Wide supply voltage range:
VCC(A): 1.1 V to 5.5 V
