74ACTQ245MTCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ245MTCX is an octal bidirectional transceiver with 3-STATE outputs, manufactured using FACT Quiet Series technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature from -40°C to +85°C. The device features non-inverting data flow controlled by Transmit/Receive (T/R) and Output Enable (OE) inputs. Propagation delay is typically 5.5 ns at 5.0 V with 50 pF load. Outputs source/sink 24 mA. It is housed in a 20-Lead Thin Shrink Small Outline Package (TSSOP).

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering code suffix 'X' confirms tape and reel packaging as indicated in the datasheet. Confirm that the component is sourced from Fairchild Semiconductor Corporation or authorized distributors, noting the current ownership status of the brand. Ensure RoHS compliance documentation aligns with JEDEC J-STD-020B standards for lead-free packages.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when low simultaneous switching noise and improved dynamic threshold performance are required compared to standard ACT devices. The TSSOP package is suitable for space-constrained surface mount designs. Ensure the system operates within the 4.5 V to 5.5 V supply range and requires TTL-compatible input thresholds.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACQ/ACTQ family of octal bidirectional transceivers. It is designed for bus-oriented applications where data directionality and high drive capability are essential. The 'Q' designation indicates the inclusion of Quiet Series technology for noise reduction, distinguishing it from standard logic families.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Standard 74ACT245 variants may be considered if noise specifications are less critical. Verify pin compatibility and electrical characteristics such as propagation delay and output current drive capabilities before substitution.
