74HC253BQX

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74HC253BQX is a dual 4-bit multiplexer housed in a DHVQFN16 (SOT763-1) package. It features two independent multiplexers, each with four binary inputs (nI0 to nI3), shared select inputs (S0 and S1), and separate active LOW output enable inputs (1OE, 2OE). The device operates within a supply voltage range of 2.0 V to 6.0 V. At 4.5 V, the maximum propagation delay is 44 ns, while at 6.0 V it is 37 ns. Total power dissipation is rated at 500 mW across an operating temperature range of -40 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix BQX corresponds to the DHVQFN16 package and reel packaging configuration. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding marking or manufacturing site transfers. Ensure the ordering part number matches the required logic family specifications before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a compact surface-mount solution is required for routing multiple digital signals. The DHVQFN16 package offers space efficiency compared to standard SOIC options. Verify that the application voltage falls within the 2.0 V to 6.0 V range and that the thermal requirements align with the 500 mW power dissipation limit for the chosen ambient temperature.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the 74HC series of high-speed CMOS logic products manufactured by Nexperia. It is functionally compatible with other 74HC253 variants but utilizes the SOT763-1 leadless package. The product data sheet revision 10 confirms the inclusion of this specific package type alongside traditional plastic small outline packages.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include the 74HC253D (SO16) and 74HC253PW (TSSOP16). These alternatives share identical logical functionality but differ in physical footprint and pinout orientation. Verify mechanical clearance and soldering compatibility when transitioning between package types.
