SN74ALVTH162245VR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVTH162245VR is a 16-bit bus transceiver from Texas Instruments' ALVTH logic family, designed for low-voltage operation. It features three-state outputs and operates within a supply voltage range of 2.3 V to 3.6 V. The device supports LVTTL input levels and provides high drive capability with a maximum low-level output current of 48 mA and a high-level output current of -24 mA at 3.3 V. It exhibits a propagation delay of 5.8 ns and functions as a non-inverting transceiver. Packaged in a TVSOP-48 format, it is rated for industrial temperatures between -40°C and +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports bidirectional data transmission across 16 channels with independent direction control
• Provides high-drive strength suitable for driving heavy capacitive loads on system buses
• Compatible with standard LVTTL logic input voltage thresholds

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data routing in general-purpose computing systems
• Memory module interface circuits requiring robust signal integrity
• Industrial control systems utilizing 3.3 V logic domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'VR' corresponds to the TVSOP-48 package variant when sourcing. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C industrial rating. Ensure input signals strictly adhere to LVTTL voltage levels to prevent undefined states or excessive power consumption during transitions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit wide bus interface is required with higher drive strength than standard LVTH devices offer. It serves as a direct functional replacement for similar 16-bit transceivers where the TVSOP-48 footprint is mandated. Consider the 5.8 ns propagation delay for timing budget analysis in high-frequency clocked systems.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ALVTH162245 series, which extends the performance envelope of the legacy ABT family by optimizing for lower voltage swings while maintaining strong output currents. It bridges the gap between standard speed and high-drive requirements in 3.3 V digital environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVTH162245DL is a documented alternative offering identical logical functionality but housed in an SSOP-48 package rather than TVSOP-48.
