SN74LVTZ244PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTZ244PWR is an octal buffer and line driver utilizing Advanced BiCMOS (ABT) technology, designed for low-voltage 3.3-V VCC operation with TTL interface capability to 5-V systems. It supports mixed-mode signal operation, allowing 5-V input and output voltages with a 3.3-V supply. The device features active bus-hold data inputs to eliminate external pullup resistors and maintains a high-impedance state during power-up and power-down. It operates within a supply voltage range of 2.7 V to 3.6 V and is characterized for temperatures from -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Advanced BiCMOS technology ensures low static power dissipation while supporting unregulated battery operation down to 2.7 V.
• Active bus-hold circuitry holds unused or floating data inputs at valid logic levels without requiring external components.
• Supports mixed-mode signal operation, enabling compatibility between 3.3-V and 5-V system environments.
• Provides high-impedance outputs during power transitions to prevent bus contention.
