SN74LV245ATDBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV245ATDBR is an octal bus transceiver from the Texas Instruments SN74LV245A series, designed for asynchronous two-way communication. It features a 20-pin SSOP package and operates within a supply voltage range of 2.7 V to 3.6 V. The device provides non-inverting logic with three-state outputs. Key electrical parameters include a maximum propagation delay of 10 ns at 3.3 V, low-level output current of 24 mA, and high-level output current of -12 mA. It supports LVTTL input levels and functions across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-20 package and tape-and-reel packaging configuration. Confirm that the 'A' designation indicates automotive qualification if required by your application standards. Ensure the supply voltage constraints (2.7 V to 3.6 V) align with your system's power rails before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 3.3 V systems with TTL-compatible devices requiring bidirectional data transfer. The LV family offers lower power consumption compared to standard CMOS alternatives. Consider the SSOP-20 package size for space-constrained designs. Verify that the 24 mA sink capability meets the load requirements of your destination circuits.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV245A family of octal bus transceivers. It shares functional similarities with the SN74LVC8T245 but differs in voltage tolerance and speed characteristics. The LV series is optimized for 3.3 V operation, distinguishing it from the broader LVC range which supports wider voltage spans. It serves as a standard interface solution in digital logic design.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LV245ADBR is a direct equivalent variant with identical electrical specifications and pinout. Check for availability of the SN74LVC8T245DBR if a wider voltage range (1.65 V to 5.5 V) is needed, noting differences in drive strength and delay.
