ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) Balanced Output Drivers: - 24mA (industrial) - 16mA (military) Reduced system switching noise Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V, TA = 25C Available in the following packages: - Industrial: SSOP, TSSOP, TVSOP - Military: CERPACK
DESCRIPTION:
The FCT162244T 16-Bit Buffer/Line Driver is for bus interface or signal buffering applications requiring high speed and low power dissipation. These devices have a flow through pin organization, and shrink packaging to simplify board layout. All inputs are designed with hysteresis for improved noise margin. The three-state controls allow independent 4-bit, 8-bit or combined 16-bit operation. These parts are plug in replacements for 54/74ABT16244 where higher speed, lower noise or lower power dissipation levels are desired. The FCT162244T has balanced output current levels and current limiting resistors. These offer low ground bounce, minimal undershoot, and controlled output fall times, reducing the need for external series terminating resistors while still providing very high speed operation for loads of less than 200pF.
