SN74LVC16244ADLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC16244ADLR is a 16-bit buffer and driver with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and features inputs tolerant to 5.5 V, facilitating mixed-mode signal operation in 3.3-V/5-V systems. The device supports live insertion and partial-power-down modes via the Ioff feature. It provides a maximum propagation delay of 4.1 ns at 3.3 V and includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Packaged in a 48-pin SSOP, it functions as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and suffix against the manufacturer's current orderable addendum to ensure correct physical dimensions and lead finish. Confirm RoHS compliance status and moisture sensitivity level ratings prior to assembly. Check for any recent product life cycle changes or alternative package options such as TSSOP or TVSOP if the SSOP variant is unavailable.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit buffering with mixed-voltage interface capabilities between 3.3-V and 5-V domains. Ensure the operating temperature range meets the application requirements, as the device supports -40°C to 125°C. Consider the drive strength and parasitic capacitance characteristics for high-speed bus applications to prevent signal integrity issues.

Buffers, Drivers, Receivers, Transceivers Part Context
