SN74ALVTH162245 具有三态输出的 2.5V/3.3V 16 位总线收发器

SN74ALVTH162245 描述

The ’ALVTH162245 devices are 16-bit (dual-octal) noninverting 3-state transceivers designed for 2.5-V or 3.3-V VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

These devices can be used as two 8-bit transceivers or one 16-bit transceiver. They allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE)\ input can be used to disable the device so that the buses are effectively isolated.

The A-port outputs, which are designed to source or sink up to 12 mA, include equivalent 30- series resistors to reduce overshoot and undershoot.

These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state

SN74ALVTH162245 特性

• State-of-the-Art Advanced BiCMOS Technology (ABT) WidebusTM Design for 2.5-V and 3.3-V Operation and Low Static-Power Dissipation
• Support Mixed-Mode Signal Operation (5-V Input and Output Voltages With 2.3-V to 3.6-V VCC)
• Typical VOLP (Output Ground Bounce)
  <0.8 V at VCC = 3.3 V, TA = 25°C
• High Drive
  • A Port = –12/12 mA at 3.3-V VCC
  • B port = –32/64 mA at 3.3-V VCC
• Ioff and Power-Up 3-State Support Hot Insertion
• Use Bus Hold on Data Inputs in Place of External Pullup/Pulldown Resistors to Prevent the Bus From Floating
• A-Port Outputs Have Equivalent 30- Series Resistors, So No External Resistors Are Required
• Flow-Through Architecture Facilitates Printed Circuit Board Layout
• Distributed VCC and GND Pins Minimize High-Speed Switching Noise
• Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
