Key Features
- 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs.
- Separate clocks for shift and storage registers, allowing for flexible data transfer.
- Serial input (DS) and serial output (Q7S) for cascading multiple devices.
- Asynchronous reset (MR) input to reset the shift register.
- Output enable (OE) input to control the output state, with high-impedance OFF-state when OE is HIGH.
- Low power dissipation and high speed operation.
- Wide operating temperature range from -40°C to 125°C.
Applications

- Communication systems: Useful in serial communication protocols where data needs to be converted between serial and parallel formats.
- Embedded systems: Ideal for microcontroller or microprocessor-based systems requiring efficient data handling.
Q & A
- What is the primary function of the 74LVC595AD112?
The primary function is to act as an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs.
- What is the voltage range for the 74LVC595AD112?
The device operates within a voltage range of 1.2 to 5.5 volts.
- What types of packages are available for the 74LVC595AD112?
The device is available in SO16, TSSOP16, and DHVQFN16 packages.
- How does the asynchronous reset (MR) input work?
A LOW on the MR input will reset the shift register.
- What is the purpose of the output enable (OE) input?
The OE input controls the output state; when OE is LOW, data from the storage register appears at the output, and when OE is HIGH, the outputs assume a high-impedance OFF-state.

Yes, the device features a serial input (DS) and a serial output (Q7S) to enable cascading.
- What logic switching levels does the 74LVC595AD112 support?
The device supports CMOS/LVTTL logic switching levels.
- What is the output drive capability of the 74LVC595AD112?
The output drive capability is ±24 mA.
