Overview
74LVC594A 8-bit shift register with output register Rev.
4 — 3 September 2020 Product data sheet 1.
General description The 74LVC594A is an 8-bit serial-in/serial or parallel-out shift register with a storage register.
Separate clock and reset inputs are provided on both shift and storage registers.
The device features a serial input (DS) and a serial output (Q7S) to enable cascading.
Data is shifted on the LOW-to-HIGH transitions of the SHCP input, and 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.
A LOW level on one of the two register reset pins (SHR and STR) will clear the corresponding register.
Inputs can be driven from either 3.
3 V or 5 V devices.
This feature allows the use of these devices as translators in mixed 3.
3 V and 5 V environments.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
This device is fully specified for partial power down applications using IOFF.
The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
