74HC4094PW,118

Shift Registers Overview

The Nexperia 74HC4094PW,118 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features separate clocks for the shift and storage registers, along with serial outputs (QS1 and QS2) for cascading. Data shifts on LOW-to-HIGH transitions of the clock input.

Shift Registers Feature Summary

• Features 3-state outputs controlled by an output enable input for bus interfacing
• Includes clamp diodes on inputs to allow current limiting resistors for voltages exceeding VCC
• Provides dual serial outputs (QS1 and QS2) to facilitate cascading under varying clock edge speeds

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register

Shift Registers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure compatibility with system voltage levels and interface requirements before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with independent storage and shift clocks is required. The TSSOP16 package suits space-constrained designs. Verify that the CMOS input levels align with the driving circuitry logic standards.

Shift Registers Part Context

This part belongs to the 74HC series of logic ICs manufactured by Nexperia. It is functionally compatible with other 74HC4094 variants but utilizes the TSSOP16 (SOT403-1) surface-mount package. It differs from the HCT variant which requires TTL-level inputs and a narrower voltage range.

Shift Registers Replacement Considerations

Cross-reference with other manufacturers offering equivalent 8-bit shift-and-store bus registers in TSSOP16 packages. Verify pinout compatibility and electrical specifications such as propagation delay and output drive current.
