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 1.65 V to 3.6 V with functional operation down to 1.2 V. Inputs accept voltages up to 5.5 V, enabling direct interfacing with 5 V logic. Data inputs feature bus hold circuits to eliminate external pull-up resistors. The component operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Provides 5 V tolerant inputs and outputs for seamless interfacing with 5 V logic systems.
• Features bus hold on all data inputs to maintain stable states without external pull-up resistors.
• Ensures high-impedance state during power-up or power-down when VCC equals 0 V.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'G,5' against official NXP documentation to confirm package details and compliance status. Confirm that the LFBGA96 package matches the required footprint dimensions of 13.5 x 5.5 mm. Ensure design compatibility with the specified operating temperature range of -40 °C to +125 °C.

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 5 V logic while powered by lower voltages. Consider the low inductance multiple power and ground pins for noise reduction in high-speed environments.
