74LVCH32245AEC/G;5

Overview

The 74LVCH32245AEC/G;5 is a 32-bit bus transceiver featuring non-inverting 3-state outputs in both send and receive directions. It includes four output enable (nOE) inputs for cascading and four direction control (nDIR) inputs. The device supports a supply voltage range of 1.2 V to 3.6 V, with functional operation starting at 1.2 V. Inputs are 5 V tolerant, accepting voltages up to 5.5 V. It operates within an ambient temperature range of -40 °C to +125 °C and is packaged in a 96-ball LFBGA.

Feature Summary

• Features 5 V tolerant inputs and outputs for interfacing with 5 V logic systems
• Includes bus hold on data inputs to eliminate the need for external pull-up resistors
• Provides high-impedance state when VCC is 0 V to support power-down isolation
• Complies with JEDEC standards for low-voltage CMOS devices

Applications

• Mixed 3.3 V and 5 V applications
• Multi-byte flow-through standard pin-out architecture implementations
• Direct interface with TTL levels

Procurement Notes

Verify the specific ordering suffix 'G;5' against the manufacturer's current documentation to confirm package details and availability status. Ensure that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Confirm compliance with relevant environmental directives such as RoHS before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring 32-bit bidirectional data transfer between buses operating at different voltage levels. The device is suitable for applications needing direct interface with TTL levels and 5 V tolerant I/O. Consider the LFBGA96 package constraints and ensure adequate thermal management for the specified temperature range.
