74LVC245AD,118

Overview

The Nexperia 74LVC245AD,118 is an octal bus transceiver with 3-state outputs housed in a 20-lead SO plastic small outline package (SOT163-1). It operates within a supply voltage range of 1.2 V to 3.6 V and supports inputs driven by 3.3 V or 5 V devices. The device features Schmitt-trigger action for tolerance of slow input transitions and includes IOFF circuitry for partial power-down applications. It complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36.

Feature Summary

• Provides bidirectional data transmission between two 8-bit buses using direction control (DIR) and output enable (OE) signals.
• Features overvoltage tolerant inputs capable of accepting voltages up to 5.5 V while operating on lower supply rails.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow current during partial power-down states.

Applications

• Mixed 3.3 V and 5 V environment translation
• Partial power-down system configurations
• Bidirectional bus driving

Procurement Notes

Verify the specific suffix '118' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm the SOT163-1 package dimensions match your PCB footprint design. Ensure the component meets RoHS compliance requirements for your target market regulations before finalizing procurement orders.

Selection Notes

Select this component when interfacing 8-bit wide buses requiring bidirectional flow control. It is suitable for designs needing direct interface with TTL levels and operation across a wide temperature range from -40 °C to +125 °C. Consider the SO20 package constraints regarding board space and thermal dissipation capabilities compared to other available package options.

Part Context

This part belongs to the 74LVC245A family of octal bus transceivers manufactured by Nexperia. It shares functional similarities with other variants like the 74LVC245APW but differs in physical packaging. The AD suffix specifically denotes the SO20 plastic small outline package variant within the broader LVC logic series portfolio.

Replacement Considerations

Check for pin-compatible alternatives such as the 74LVC245APW if TSSOP packaging is acceptable. Verify electrical specifications against other manufacturers' octal transceivers ensuring voltage ranges and drive currents align with system requirements.
