74ACT251MTC

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74ACT251MTC is an 8-input digital multiplexer housed in a 16-lead Thin Shrink Small Outline Package (TSSOP). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -40°C to +85°C. The device features TTL-compatible inputs, providing high-speed data selection from eight sources to a single bit output. It includes both true and complementary outputs with 3-STATE capability, allowing for bus expansion. The ACT series offers reduced quiescent current and robust drive capabilities.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering code suffix to confirm package type and tape/reel availability. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the component meets all absolute maximum ratings for supply voltage and input/output currents during system design validation.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when TTL-compatible inputs are required alongside high-speed multiplexing. The 3-STATE outputs facilitate complex bus architectures. Verify that the TSSOP-16 package fits the PCB layout constraints. Consider the ACT series specifications for lower power consumption compared to older logic families while maintaining speed.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AC/ACT family of high-speed CMOS logic devices. It serves as an 8-to-1 data selector, distinct from buffer or transceiver variants within the same logical family. The MTC suffix specifically denotes the 16-lead TSSOP physical package format used for surface-mount applications.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Cross-reference with other manufacturers' 74ACT251 equivalents. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive strength before substitution.
