Overview
The 74LVC2245AD,112 is an octal bus transceiver manufactured by Nexperia (formerly NXP) in a 20-lead SOIC package. It operates within a supply voltage range of 1.2 V to 3.6 V and features 5 V tolerant inputs and outputs. The device includes integrated 30 Ω series termination resistors and provides three-state outputs controlled by Output Enable (OE) and Direction (DIR) pins. It supports partial power-down via IOFF circuitry and complies with JEDEC standards for low-voltage CMOS logic.
Feature Summary
- Integrated 30 Ω series termination resistors for signal integrity
- 5 V tolerant inputs and outputs for mixed-voltage environments
- IOFF circuitry enables safe partial power-down operation
- Schmitt-trigger action at all inputs for noise immunity
Applications
- Memory mapping
- Clock drivers
- Bus-oriented architectures
Procurement Notes
Verify the ordering suffix '112' corresponds to the tape-and-reel packaging format specified in the official datasheet. Confirm that the manufacturer designation aligns with current Nexterra product lines, as corporate branding transitions may affect documentation sources. Ensure the component meets RoHS compliance requirements for your specific manufacturing region.
Selection Notes
Select this component when designing systems requiring bidirectional data transfer between 3.3 V and 5 V domains. The integrated termination resistors make it suitable for high-speed applications without external components. Verify that the required propagation delay and drive current meet the system timing constraints under the intended operating temperature range.
Part Context
This part belongs to the 74LVC2245A family of octal transceivers. The 'AD' suffix indicates the SO20 plastic small outline package variant. The family is designed for low-voltage CMOS applications, offering compatibility with TTL levels while maintaining low power consumption across the wide supply voltage range.
Replacement Considerations
Direct pin-compatible alternatives include the 74LVC2245APW (TSSOP20) and 74LVC2245ABQ (DHVQFN20). These variants share identical electrical specifications but differ in physical package dimensions and thermal characteristics.
