• 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)

• Bus Hold retains last active bus state during 3-state

• Eliminates the need for external pull up resistors

• Available in SSOP and TSSOP packages

The FCT162H501T has "Bus Hold" which retains the input's last state

whenevertheinputgoestohighimpedance. Thisprevents"floating"inputsand

eliminatestheneedforpull-up/downresistors.
