IDT74FCT162H952AT/CT/ET
0.5 MICRON CMOS Technology
High-speed, low-power CMOS replacement for ABT functions
Typical t

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 FCT162H952T 16-bit registered transceiver is built using advanced
dual metal CMOS technology. These high-speed, low-power devices are
organized as two independent 8-bit D-type registered transceivers with
separate input and output control for independent control of data flow in either
direction. For example, the A-to-B Enable (xCEAB) must be low to enter data
from the A port. xCLKAB controls the clocking function. When xCLKAB toggles
from low-to-high, the data present on the A port will be clocked into the register.
xOEAB performs the output enable function on the B port. Data flow from the
B port to A port is similar but requires using xCEBA, xCLKBA, and xOEBA inputs.
Full 16-bit operation is achieved by tying the control pins of the independent
transceivers together.
The FCT162H952T has "Bus Hold" which retains the input's last state
whenever the input goes to high impedance. This prevents "floating" inputs and
eliminates the need for pull-up/down resistors.
