PI74LVCC3245ALE

Translators, Level Shifters Overview

The PI74LVCC3245ALE is an 8-bit bidirectional bus transceiver manufactured by Diodes Incorporated, utilizing advanced submicron CMOS technology. It features two separate power supply rails: VCCA operates from 2.7V to 3.6V, while VCCB supports 3V to 5.5V, enabling voltage translation between 3.3V and 5V environments. The device provides non-inverting data transfer with configurable output voltage and 3-state outputs. Key electrical characteristics include a propagation delay of approximately 1ns to 7.2ns depending on direction and load, and high drive currents of ±24mA. It operates within an industrial temperature range of –40°C to +85°C.

Translators, Level Shifters Feature Summary

• Supports asynchronous two-way communication between data buses with independent A and B port voltage domains.
• Features 3-state outputs controlled by OE and DIR pins for effective bus isolation and direction management.
• Provides robust ESD protection exceeding JESD22 standards for Human-Body and Machine Models.

Translators, Level Shifters Applications

• Asynchronous two-way communication between data buses
• Voltage translation between 3.3V and 5V environments
• Memory and flash card interfaces

Translators, Level Shifters Procurement Notes

Verify the component status as discontinued or obsolete through official manufacturer channels before procurement planning. Confirm that the specific ordering suffix 'ALE' corresponds to the Pb-free 24-pin TSSOP package variant. Ensure compatibility with existing design constraints regarding the dual-supply voltage requirements and thermal performance specifications.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring bidirectional level shifting between 2.7V–3.6V and 3V–5.5V logic domains. Consider the 24-pin TSSOP package for surface mount applications. Evaluate the propagation delay and drive current capabilities against the specific bus loading requirements to ensure signal integrity across the operating temperature range.

Translators, Level Shifters Part Context

This part belongs to the PI74LVC series of logic circuits produced using advanced submicron CMOS technology. It is functionally similar to other octal bus transceivers in the industry but is distinguished by its specific dual-supply configuration and Pericom/Diodes Incorporated manufacturing heritage. The 'ALE' suffix denotes the lead-free version of the standard PI74LVCC3245AL in the TSSOP package.
