74LVCH16245AEV,118

Overview

The Nexperia 74LVCH16245AEV,118 is a 16-bit bus transceiver with 3-state outputs. It supports a supply voltage range of 1.2 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device includes IOFF circuitry for partial power-down applications and active bus hold on data inputs. It operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Active bus hold on all data inputs eliminates the need for external pull-up resistors.
• IOFF circuitry disables outputs to prevent damaging backflow current during partial power-down.
• Schmitt-trigger action at all inputs provides tolerance for slower input rise and fall times.

Applications

• Mixed 3.3 V and 5 V environments
• Partial power-down applications

Procurement Notes

Verify the specific package type against the ordering information table in the datasheet. Confirm that the suffix matches the required lead pitch and body width specifications. Ensure the component meets the specified JEDEC standards for the intended operating voltage range before integration into the design.

Selection Notes

Select this component when a 16-bit bidirectional interface is required with 5 V tolerance. The LVCH variant is appropriate if active bus hold functionality is needed to manage unused inputs without external components. Verify compatibility with the system's supply voltage constraints and thermal requirements.

Part Context

This part belongs to the 74LVC/LVCH16245A family of 16-bit bus transceivers. It shares functional characteristics with variants such as the 74LVCH16245ADGG but differs in physical packaging. The AEV designation indicates a specific package configuration distinct from the TSSOP or TVSOP options listed in the official ordering information.
