说明

The SN74ABTE16246 is an 11-bit noninverting transceiver designed for asynchronous two-way communication between buses. This device has open-collector and 3-state outputs. The device allows 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. When OE\ is low, the device is active.

The B port has an equivalent 25- series output resistor to reduce ringing. Active bus-hold inputs on the B port hold unused or floating inputs at a valid logic level.

The A port provides for the precharging of the outputs via V_CCBIAS, which establishes a voltage between 1.

特性

• Member of the Texas Instruments Widebus™ Family
• Supports the VME64 ETL Specification
• Reduced TTL-Compatible Input Threshold Range
• High-Drive Outputs (I_OH = –60 mA, I_OL = 90 mA) Support Equivalent 25- Incident-Wave Switching
• V_CC BIAS Pin Minimizes Signal Distortion During Live Insertion
• Internal Pullup Resistor on OE\ Keeps Outputs in High-Impedance State During Power Up or Power Down
• Distributed V_CC and GND Pins Minimize High-Speed Switching Noise
• Equivalent 25- Series Damping Resistor on B Port
• Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors
