SN74LVC16245ADL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC16245ADL is a 16-bit bus transceiver with 3-state outputs from the Texas Instruments LVC family. It operates on a supply voltage range of 1.65 V to 3.6 V and features inputs tolerant to 5.5 V, supporting mixed-mode signal operation in 5-V/3.3-V systems. The device provides a maximum propagation delay of 4 ns at 3.3 V and includes Ioff circuitry for partial-power-down mode. It is housed in a 48-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest Package Option Addendum to confirm the exact packaging type (Tube vs. Tape & Reel) and material finish. Ensure the selected variant matches the required operating temperature range and moisture sensitivity level for the intended assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing mixed-voltage systems requiring 5-V tolerance on inputs while powered by lower voltages such as 3.3 V or 1.8 V. The high drive capability and low propagation delay make it suitable for high-speed data transmission applications where bus isolation and partial-power-down protection are necessary.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC16245A series within the Widebus family. It is functionally compatible with other variants in the same logic family that share the 16-bit bidirectional transceiver architecture, differing primarily in package style, manufacturing revision, or reel specifications.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature benefit partial-power-down applications?

The Ioff circuitry automatically disables the outputs when the device is powered down, preventing damaging current backflow through the device from live buses.

Can this device be used for voltage translation between 5-V and 3.3-V systems?

Yes, the inputs accept voltages up to 5.5 V at any valid VCC, allowing the device to operate in mixed 3.3-V/5-V system environments.
