74LVCH245AD,112

Overview

The Nexperia 74LVCH245AD,112 is an octal bus transceiver with 3-state outputs in a SO20 plastic small outline package. It operates on 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 Schmitt-trigger action for slow input transitions and bus hold circuitry on all data inputs. It supports partial power-down applications via IOFF circuitry and complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36.

Feature Summary

• Bus hold circuitry on all data inputs
• IOFF circuitry for partial power-down mode operation
• Schmitt-trigger action at all inputs

Applications

• Mixed 3.3 V and 5 V environments
• Octal bidirectional bus interface
• Partial power down applications

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the SO20 (SOT163-1) package variant as documented in the official Nexperia datasheet. Confirm that the required temperature range covers -40 °C to +125 °C for your application environment. Ensure design compatibility with the specified JEDEC standards and ESD protection levels before finalizing procurement.

Selection Notes

Select this component when an octal transceiver with integrated bus hold functionality is required. The LVCH logic family provides direct interface capability with TTL levels while maintaining CMOS low-power consumption. The wide supply voltage range allows flexibility in mixed-voltage system designs without requiring additional level shifting components.

Part Context

This part belongs to the 74LVC/LVCH245A series of octal bus transceivers. The 'H' designation indicates the inclusion of bus hold circuitry on data inputs, distinguishing it from the standard 74LVC245A variant. The AD suffix identifies the specific SO20 package type within the broader product family.

Replacement Considerations

The 74LVC245AD,112 serves as a functional equivalent to the non-bus-hold 74LVC245AD variant where bus holding is not required. Verify pinout and electrical characteristics against other octal transceivers in the 74LVC or 74LVCH families before substitution.
