FEATURES:
• 0.5 MICRON CMOS Technology
• High-speed, low-power CMOS replacement for ABT functions
• Typical tSK(o) (Output Skew) < 250ps
• Low input and output leakage 1µA (max.)
• 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 = 25°C
• Available in the following packages:
– Industrial: SSOP, TSSOP
– Military: CERPACK
DESCRIPTION:
The FCT162245T 16-bit transceiver is built using advanced dual metal
CMOS technology. These high-speed, low-power transceivers are ideal for
synchronous communication between two buses (A and B). The Direction and
OutputEnablecontrolsoperatethesedevicesaseithertwo independent 8-bit
transceivers or one 16-bit transceiver. The direction control pin (xDIR) controls
the direction of data flow. The output enable pin (xOE) overrides the direction
control and disables both ports. All inputs are designed with hysteresis for
improved noise margin.
The FCT162245T has balanced output drive with current limiting resistors.
Thisofferslowgroundbounce,minimalundershoot, andcontrolledoutputfall
times–reducing the need for external series terminating resistors. The
FCT162245T is a plug-in replacement for the FCT16245T and ABT16245 for
on-board interface applications.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
