74HC253PWHL

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74HC253PWHL is a dual 4-bit multiplexer housed in a TSSOP16 (SOT403-1) package. It features two independent multiplexers, each with four binary inputs and shared select lines. The device operates within a supply voltage range of 2.0 V to 6.0 V for the HC variant and 4.5 V to 5.5 V for the HCT variant. Propagation delay reaches 265 ns at 2.0 V and 53 ns at 4.5 V. It includes separate active-low output enable inputs and supports an operating temperature from -40 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'HL' against official Nexperia documentation to confirm exact manufacturing lot or marking variations. Ensure the TSSOP16 package type matches the design footprint requirements. Confirm that the ambient temperature rating aligns with the application's thermal constraints before finalizing procurement specifications.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a dual-channel multiplexing solution with three-state bus interfacing is required. The wide supply voltage range accommodates various logic families. Verify input voltage levels match the source logic; use the HCT version for TTL compatibility and the HC version for broader voltage flexibility. Ensure the TSSOP16 package fits the available PCB space.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74HC/HCT253 family of dual 4-input multiplexers. It shares functional characteristics with other variants like the SO16 and DHVQFN16 packages but differs in physical dimensions and thermal properties. The PWHL designation specifically identifies the Thin Shrink Small Outline Package configuration used in surface-mount applications.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct pin-compatible replacements include the 74HC253D (SO16) and 74HC253BQ (DHVQFN16). Verify package dimensions and thermal dissipation capabilities when substituting. Cross-reference ordering information to ensure the selected alternative maintains the same logic family and electrical specifications.
