SN74GTLPH1645DGVR

Translators, Level Shifters Overview

The SN74GTLPH1645DGVR is a mixed-signal voltage level translator manufactured by Texas Instruments. It belongs to the GTLPH logic series and facilitates bidirectional data transfer between LVTTL and GTLP signaling domains. The device features two independent circuits, each providing eight channels for a total of sixteen bits of translation capability. It is housed in a TVSOP-56 surface-mount package designed for high-density applications. The component operates within a supply voltage range of 3.15 V to 3.45 V and supports an operating temperature range from -40 °C to +85 °C. Typical propagation delay is specified at 9.4 ns.

Translators, Level Shifters Feature Summary

Translators, Level Shifters Procurement Notes

Verify the specific suffix DGVR against official Texas Instruments documentation to confirm the tape-and-reel packaging configuration. Ensure that the required supply voltage constraints of 3.15 V to 3.45 V are strictly maintained in the target design. Confirm that the GTLPH series designation aligns with the intended signal integrity requirements for the application environment.

Translators, Level Shifters Selection Notes

Select this component when interfacing LVTTL sources with GTLP loads requiring bidirectional data flow. The dual-circuit architecture allows for flexible pinout configurations within the TVSOP-56 footprint. Consider the 9.4 ns propagation delay when designing timing-critical paths. Verify compatibility with the 3.15 V to 3.45 V power domain before integration into the system schematic.

Translators, Level Shifters Part Context

This part is a member of the Texas Instruments GTLPH family, specialized for translating between Low Voltage Transceiver Transistor Logic and Ground Terminated Logic. Unlike standard logic gates, these devices manage distinct voltage domains to ensure reliable communication between disparate subsystems. The TVSOP-56 package provides a compact solution for maintaining signal integrity in dense printed circuit board layouts.
