SN74AC245NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AC245NSR is an octal bus transceiver manufactured by Texas Instruments, belonging to the AC logic series. It features eight non-inverting channels with three-state outputs, designed for asynchronous two-way communication between data buses. The device operates within a supply voltage range of 2 V to 6 V and supports CMOS input and output levels. Key electrical parameters include a propagation delay of 7 ns, maximum power supply current of 4 uA, and output drive currents of 24 mA in both high and low states. It is housed in a TSSOP-20 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SR' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications and moisture sensitivity level. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the operating temperature range aligns with your system's environmental conditions before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring high-speed octal data transfer with minimal external timing constraints. The AC logic family offers a balance of speed and power consumption suitable for general-purpose digital applications. Ensure the design accommodates the 2 V to 6 V supply voltage range and verify that the TSSOP-20 footprint matches the PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AC245 family of octal bus transceivers from Texas Instruments. It is functionally similar to other variants like the CD74AC245M but differs in packaging and specific electrical characteristics such as propagation delay and supply voltage limits. The AC series is distinct from LVC or ACT families in terms of voltage tolerance and switching speed.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for pin-compatible alternatives such as the SN74AC245PWR or SN74LVC245AIPWREP if different packaging or voltage ranges are required. Verify that any substitute maintains the same octal configuration and three-state output functionality.
