Shift Registers Procurement Notes

Verify the exact part number MC74LV594ADTR2G against official onsemi documentation to confirm the LV series designation and TSSOP-16 packaging. Ensure compatibility with 2.0 V to 3.6 V supply rails. Check for RoHS compliance status in the latest datasheet. Confirm lead times and availability directly with authorized distributors as inventory levels fluctuate.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with 3-state outputs is required for low-voltage (2.0 V–3.6 V) applications. It is suitable for designs needing serial-to-parallel conversion with independent storage control. Compare propagation delays and static current specifications against system timing requirements. Ensure the TSSOP-16 package fits the PCB layout constraints.

Shift Registers Part Context

This part belongs to the MC74LVX/LV family of CMOS logic devices manufactured by onsemi. These components are designed for low-voltage digital applications, offering high noise immunity and low power consumption. The LV series typically bridges the gap between standard CMOS and LVC technologies, providing robust performance in portable and battery-operated electronics.

Shift Registers FAQ

What is the function of the MR pin?

The MR (Master Reset) pin asynchronously resets all eight flip-flops in the shift register to a low state when driven low.

How does the OE pin affect operation?

The OE (Output Enable) pin controls the 3-state outputs. When OE is low, outputs are active; when high, outputs are in a high-impedance state.
