74LVC245AE4PG

Overview

The IDT 74LVC245AE4PG is an octal bus transceiver and voltage level shifter belonging to the 74LVC logic family. It features eight bidirectional data channels with three-state outputs, designed for high-speed data transfer between different voltage domains. The device supports a wide supply voltage range of 1.65V to 3.6V, enabling compatibility with various low-voltage logic systems. It utilizes a 20-pin SSOP package suitable for surface-mount applications.

Feature Summary

• Provides bidirectional data transmission across eight independent channels
• Supports voltage level shifting between different logic power domains
• Features three-state outputs to prevent bus contention during inactive states

Applications

• Bidirectional data bus driving in embedded systems
• Voltage translation between 1.8V, 2.5V, and 3.3V logic levels
• Memory interface expansion in portable electronic devices

Procurement Notes

Verify the specific suffix 'E4PG' against manufacturer documentation to confirm pinout and package dimensions. Ensure the component meets required environmental standards such as RoHS compliance before integration into final assemblies.

Selection Notes

Select this component when designing circuits requiring robust bidirectional communication between mixed-voltage logic blocks. Consider the 20-pin SSOP footprint for space-constrained layouts and verify that the operating voltage aligns with the target system's power rails.
