74AC245PC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74AC245PC is an octal bidirectional transceiver belonging to the 74AC logic series. It features eight non-inverting buffers with three-state outputs, designed for bus-oriented applications. The device operates within a supply voltage range of 2V to 6V and utilizes a 20-pin DIP package. Key electrical characteristics include a maximum propagation delay of 7ns at specific load conditions and output current capabilities of ±24mA at both A and B ports. It supports TTL input levels and functions across an operating temperature range from -40°C to +85°C.

• Digital signal routing in computing architectures
• General-purpose bidirectional data buffering

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches requirements, as 'PC' typically denotes a 20-pin DIP configuration distinct from surface-mount variants like SCX or MTCX. Confirm the specific suffix aligns with the desired lead time and packaging format. Ensure compatibility with existing board layouts regarding pin pitch and footprint dimensions before finalizing orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed CMOS performance is required with robust drive strength. The AC series offers faster switching speeds compared to standard HC or HCT families while maintaining similar power consumption profiles. Verify that the system voltage falls within the 2V to 6V operational range and that TTL-compatible inputs are necessary for interfacing with legacy logic devices.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the widely adopted 74AC family of high-speed CMOS logic devices manufactured by onsemi. It serves as a direct functional equivalent to other manufacturers' 74AC245 implementations, facilitating cross-brand sourcing flexibility. The device is integral to designs requiring reliable, high-current bidirectional data transfer over parallel buses.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include MC74AC245DWR2G (SOIC-20) and 74AC245MTCX (TSSOP-20). These alternatives share identical logical functionality but differ in physical package geometry. Verify pinout compatibility and thermal management requirements when transitioning between through-hole and surface-mount technologies.
