Overview
The onsemi 74LVT16240MEA is a low-voltage 16-bit inverting buffer and line driver featuring 3-STATE outputs. It operates within a supply voltage range of 2.7V to 3.6V and supports input voltages up to 5.5V, enabling TTL interface compatibility with 5V systems. The device utilizes advanced BiCMOS technology for high-speed operation while maintaining low power dissipation. It features nibble control with four independent Output Enable inputs (OEn) that can be shorted for full 16-bit operation. The component is housed in a 48-Lead Small Shrink Outline Package (SSOP).
Feature Summary
- Provides 3-STATE output capability controlled by four independent OEn inputs for flexible bus-oriented applications.
- Supports live insertion and extraction without causing glitches due to power-up/down high impedance behavior.
- Features 5V tolerant inputs allowing direct interfacing between 3.3V logic and 5V environments.
Applications
- Memory address drivers
- Clock drivers
- Bus-oriented transmitter/receiver circuits
Procurement Notes
Verify the specific package variant required, as the 74LVT16240MEA denotes the SSOP package. Confirm availability status, as this component may be subject to End-of-Life notices or limited stock depending on current distributor inventories. Ensure design-in compliance with the manufacturer's life support policy restrictions if intended for critical medical or safety systems.
Selection Notes
Select the 74LVT16240MEA when a 16-bit inverting buffer with 3-STATE outputs is required in an SSOP package. Choose this part over the LVTH variant if bushold functionality is not needed. Ensure the application requires 5V tolerant inputs and operates within the specified 2.7V to 3.6V supply range. Verify that the nibble control architecture fits the system design requirements.
Part Context
This component belongs to the 74LVT logic family, designed for low-voltage digital applications. It is functionally compatible with the standard 74 series 16240 but optimized for lower power consumption and higher speed using BiCMOS technology. The device serves as a bridge between different voltage domains in digital systems.
Replacement Considerations
Check for functional equivalents from other manufacturers offering 16-bit inverting buffers with 3-STATE outputs in SSOP packages. Verify pinout compatibility and electrical specifications such as propagation delay and drive current before substitution.
FAQ
Does the 74LVT16240MEA include bushold inputs?
No, the 74LVT16240MEA does not include bushold inputs. This feature is available only in the 74LVTH16240 variant.
How is the 3-STATE control managed in the 74LVT16240MEA?
The device uses four independent Output Enable (OEn) inputs to control nibbles of data. These pins can be shorted together to enable full 16-bit operation.
