74LVC595A

General description

The 74LVC595A 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 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 I_OFF. The I_OFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.

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 will always be one clock pulse ahead of the storage register.

The shift register has a serial input (DS) and a serial output (Q7S) for cascading purposes. It is also provided with asynchronous reset input MR (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.

Features

• 5 V tolerant inputs/outputs for interfacing with 5 V logic
• Wide supply voltage range from 1.2 V to 3.6 V
• CMOS low-power consumption
• Direct interface with TTL levels
• Balanced propagation delays
• All inputs have Schmitt-trigger action
• Complies with JEDEC standard JESD8-B/JESD36
• ESD protection:
  • HBM JESD22-A114-D exceeds 2000 V
  • CDM JESD22-C101-C exceeds 1000 V
• Specified from -40 Cel to +85 Cel and -40 Cel to +125 Cel.
