V62/05612-01YE

Overview

The V62/05612-01YE is a military-enhanced, 16-bit dual-octal noninverting bus transceiver from the SN74ALVC164245-EP family. It features independent supply rails: VCCA operates at 2.3 V to 3.6 V, and VCCB operates at 3 V to 5.5 V. The device provides asynchronous communication between data buses with a maximum propagation delay of 5.8 ns at 3.3 V. It offers ±24 mA output drive capability and includes three-state outputs. Control inputs are referenced to the VCCA voltage.

Feature Summary

• Supports translation between 2.5-V to 3.3-V environments or 3.3-V to 5-V environments via separate supply rails
• Provides high-speed asynchronous communication between data buses with low propagation delay
• Includes latch-up performance exceeding 250 mA per JESD 17 standard for robust operation

Applications

• Asynchronous communication between mixed-voltage data buses
• Translation between 2.5-V and 3.3-V logic domains
• Translation between 3.3-V and 5-V logic domains

Procurement Notes

Verify that the specific ordering suffix corresponds to the TSSOP (DGG) package variant. Confirm the operating temperature range matches the required application environment, as military-grade variants typically support extended ranges compared to commercial versions. Ensure compliance with export control regulations if applicable.

Selection Notes

Select this component when interfacing systems requiring bidirectional level shifting between 2.5-V, 3.3-V, and 5-V logic families. The dual-supply architecture allows flexible voltage domain integration. Verify that the input transition rates remain within specified limits to ensure signal integrity across the translated voltage levels.

Part Context

This part belongs to the Texas Instruments Widebus family of level-shifting transceivers. It is an enhanced product (EP) version of the SN74ALVC164245, designed for reliability in demanding environments. The V62 designation indicates it is a qualified military/aerospace grade component manufactured under controlled baseline conditions.

FAQ

How does the device handle power-up sequences?

To prevent excessive supply current or bus contention during power-up, ground should be connected first, followed by powering up the control side (VCCA). The OE input must be tied to VCCA through a pullup resistor to ensure a high-impedance state.

What is the function of the DIR and OE pins?

The Direction (DIR) pins determine the data flow direction (A to B or B to A), while the Output Enable (OE) pins control whether the outputs are active or in a high-impedance state. Both sets of control circuitry are powered by VCCA.
