mA IOH, 64mA IOL) – Power off disable outputs permit “live insertion” – Typical VOLP (Output Ground Bounce) < 1.0V at VCC = 5V, TA = 25°C • Featur es for FCT162841AT/BT/CT/ET: – Balanc ed Output Drivers: ±24mA (commercial), ±16mA (military) – Reduced system s witching noise – Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V,TA = 25°C DESCRIPTION: The FCT16841AT/BT/ CT/ET and FCT162841AT/BT/CT/ ET 20-bit transparent D-type latches are built us ing advanced dual metal CMOS technology . These high-speed, low-power latches a re ideal for temporary storage of data. They can be used for implementing memo ry address latches, I/O ports, and bus drivers. The Output Enable and Latch En able controls are organized to operate each device as two 10-bit latches or on e 20-bit latch. Flow-through organizati on of signal pins simplifies layout. Al l inputs are designed with hysteresis f or improved noise margin. The FCT16841A T/BT/CT/ET are ideally suited for drivi ng high-capacitance loads and low-imped ance backplanes. The output buffers are designed with power off disable capabi lity to allow "live insertion" of board s when used as backplane drivers. The F CT162841AT/BT/CT/ET have balanced outpu t drive with current limiting resistors . This offers low ground bounce, minimal undershoot, and controlled out
