74LVC594A-Q100: 8-bit shift register with output register

The 74LVC594A-Q100 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 input can be driven from either 3.3 V or 5 V devices. This feature allows the use of this device in a mixed 3.3 V and 5 V environment.

This device is fully specified for partial Power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.

The shift register has a serial input (DS) and a serial output (Q7S) for cascading purposes. 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. A LOW level on one of the two register reset pins (SHR and STR) clears the corresponding register.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
