Key Features
- Separate clock and reset inputs for shift and storage registers.
- Serial input (DS) and serial output (Q7S) for cascading.
- Data shifted on LOW-to-HIGH transitions of the SHCP input, and transferred to the storage register on a LOW-to-HIGH transition of the STCP input.
- LOW level on SHR or STR resets the corresponding register.
- Inputs can be driven from either 3.3 V or 5 V devices, making it suitable for mixed voltage environments.
- Schmitt-trigger action at all inputs for tolerance of slower input rise and fall times.
- IOFF circuitry for partial power-down mode operation, preventing backflow current when powered down.
- Overvoltage tolerant inputs up to 5.5 V.
- CMOS low power dissipation.
- Direct interface with TTL levels.
- Complies with JEDEC standards: JESD8-7A, JESD8-5A, JESD8-C/JESD36.
