SN74LVT245DBLE

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT245DBLE is an octal bus transceiver from the LVT logic series, manufactured by Texas Instruments. It operates at a supply voltage of 2.7 V to 3.6 V and features 3-state outputs with non-inverting polarity. The device provides TTL interface capability for 5-V systems despite low-voltage operation. Key electrical parameters include a propagation delay of 2.3 ns, maximum power supply current of 5 mA, and output drive currents of 64 mA (low) and -32 mA (high). It functions within a temperature range of -40°C to +85°C and is housed in a 20-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transmission between two buses using eight independent channels.
• Enables direct interfacing between 3.3-V components and legacy 5-V TTL systems.
• Offers high-drive 3-state outputs to manage bus loading effectively.

Buffers, Drivers, Receivers, Transceivers Applications

• Memory mapping applications requiring level translation
• Clock drivers and buffer circuits
• Bidirectional bus architecture interconnects

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E' indicates environmental compliance status according to manufacturer documentation. Confirm the SSOP-20 package dimensions match PCB footprint requirements. Ensure input voltage levels remain within specified limits to prevent latch-up or damage during system integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require mixing 3.3-V logic with 5-V TTL inputs. The LVT series offers faster switching speeds compared to standard LS logic while maintaining lower power consumption. Verify that the application does not exceed the maximum operating temperature or voltage ratings defined in the datasheet.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVT245B family of octal bus transceivers. It serves as a bridge for data transfer between different voltage domains. The device is widely used in embedded systems where mixed-voltage compatibility is essential for reliable communication between microcontrollers and peripheral devices.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74LVT245BDWRE4 as a potential alternative if reel packaging is required instead of tube or cut tape. Verify pinout compatibility before substituting with other LVT series transceivers.
