74LVT16245MTDX

Overview

The onsemi 74LVT16245MTDX is a low-voltage 16-bit bidirectional transceiver with 3-STATE outputs, packaged in a 48-Lead Thin Shrink Small Outline Package (TSSOP). 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 in 5V environments. The device features byte-controlled operation with separate control inputs for each byte, allowing independent or combined full 16-bit functionality. Designed with advanced BiCMOS technology, it delivers high-speed performance comparable to 5V ABT logic while maintaining low power dissipation.

Feature Summary

• Supports live insertion and extraction without bus interference
• Provides glitch-free bus loading during power-up and power-down cycles
• Features 3-STATE outputs capable of sourcing and sinking significant current

Applications

• Bus-oriented applications requiring byte-controlled data transfer
• Low-voltage (3.3V) systems interfacing with 5V TTL environments
• High-speed data routing in portable electronics and industrial systems

Procurement Notes

Verify the specific ordering suffix 'X' confirms tape and reel packaging availability as indicated in official documentation. Confirm that the component corresponds to the standard LVT16245 variant rather than the LVTH16245 bushold version unless explicitly specified. Ensure compliance with RoHS directives and check for any end-of-life notices or production change notifications relevant to this specific package type.

Selection Notes

Select this component when designing systems requiring 16-bit bidirectional data transfer between 3.3V and 5V domains. The TSSOP package is suitable for surface-mount applications needing compact footprints. Consider the LVTH16245 variant if bushold functionality is required to eliminate external pull-up resistors. Verify that the operating temperature range of -40°C to +85°C meets environmental requirements.

Part Context

This component belongs to the 74LVT series of low-voltage CMOS logic devices. It is functionally compatible with the standard 74 series 16245 but optimized for lower voltage operation. The device is manufactured using BiCMOS technology to balance speed and power efficiency. It is part of a broader family of bus transceivers designed for high-density digital systems.

Replacement Considerations

Direct substitutes include other 74LVT16245 variants from different manufacturers offering identical pinouts and electrical characteristics. Ensure replacement parts maintain the same 48-TSSOP package dimensions and support the required 3.3V to 5V level shifting capabilities.
