74AC245MTCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74AC245MTCX is an octal bus transceiver in the 74AC logic series, housed in a 20-pin TSSOP package. It operates with a supply voltage range of 2V to 6V and features non-inverting bidirectional data flow controlled by a single direction pin. The device provides three-state outputs compatible with TTL input levels. Key electrical parameters include a maximum propagation delay of 7ns at capacitive load, with output drive capabilities of 24mA for both high and low states. It functions within an industrial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'MTCX' corresponds to the Tape and Reel packaging format when ordering. Confirm that the required quantity aligns with the manufacturer's standard reel size of 2,500 units or check availability for cut tape options if partial quantities are needed. Ensure the design accommodates the 30-week standard lead time indicated for this component variant.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with AC-speed performance is required in a compact surface-mount package. It serves as a suitable replacement for older HC-series devices where higher speed and stronger drive current are necessary. Verify that the 2V minimum supply voltage meets the lowest operating condition of the target system.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AC family of high-speed CMOS logic devices manufactured by onsemi. It shares functional compatibility with other 74AC245 variants but differs in packaging and trailing suffixes. The MTCX designation specifically identifies the TSSOP-20 form factor with tape-and-reel delivery, distinguishing it from SOIC or through-hole alternatives.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers include 74AC245SCX (SOIC-20 package) and MM74HC245AWM (HC series alternative). Note that HC series parts have significantly lower drive current and slower propagation delays compared to the AC series.
