74LVT162244MTDX

Overview

The onsemi 74LVT162244MTDX is a discontinued low-voltage 16-bit buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 2.7V to 3.6V, with inputs tolerant up to 5.5V for TTL interface compatibility. The device utilizes an advanced BiCMOS technology to achieve high-speed operation while maintaining low power dissipation. Key electrical characteristics include propagation delays ranging from 1.2ns to 4.8ns depending on voltage conditions, output currents of ±12mA, and input capacitance of 4pF. It is housed in a 48-lead Thin Shrink Small Outline Package (TSSOP).

Feature Summary

• Integrated equivalent series resistance in outputs reduces overshoot and undershoot without external termination resistors.
• Nibble-controlled architecture allows independent or combined 8-bit and 16-bit operation via control pin configuration.
• Power-up and power-down states ensure glitch-free bus loading through high-impedance isolation.
• Input interface capability supports systems operating at 5V VCC despite the device's low-voltage design.

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitters and receivers

Procurement Notes

This component is officially discontinued and not recommended for new designs. Buyers must verify current availability status directly with onsemi representatives. Sourcing may involve obsolete stock or alternative lifecycle management options rather than standard manufacturing channels.

Selection Notes

Select this part only for legacy system maintenance where specific form factor and electrical parameters are required. Verify that the TSSOP-48 package dimensions match existing board layouts. Confirm that the 2.7V to 3.6V operating range aligns with the target system power rails before integration.

Part Context

The 74LVT162244 belongs to the LVT logic family, designed for low-voltage applications requiring high speed. It is functionally compatible with the 74 series 162244 but offers improved performance through BiCMOS fabrication. The MTDX suffix indicates the specific 48-lead TSSOP packaging variant available in tape and reel format.

Replacement Considerations

Verify functional equivalents such as the 74LVTH162244 for bushold input features. Check for other 16-bit buffers in the LVX or LVC families if voltage levels differ. Consult onsemi documentation for updated cross-reference lists due to the discontinued status.
