Product Description: SN74LVCH16543ADGGR from Texas Instruments

The SN74LVCH16543ADGGR is a high-performance, 16-bit registered transceiver from Texas Instruments, a renowned name in the semiconductor industry. This device is designed for low-voltage (3.3V) VCC operation, but with the capability to provide a TTL interface to a 5V system environment.

Key Features

• Operates From 1.65 V to 3.6 V
• Max tpd of 6.5 ns at 3.3 V
• ±24-mA Output Drive at 3.3 V
• Ioff Supports Live Insertion, Partial-Power-Down Mode, and Back-Drive Protection
• Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors
• Distributed VCC and GND Pins Minimize High-Speed Switching Noise

The SN74LVCH16543ADGGR is designed for asynchronous communication between data buses. The device transmits data 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 device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

Applications

• Telecommunications
• Networking
• Servers
• Computers and Peripherals
• Industrial Automation

The SN74LVCH16543ADGGR is available in a TSSOP package and is characterized for operation from –40°C to 85°C. With its high drive capabilities, this device is perfect for interfacing with high-capacitance loads or low-impedance backplanes.
