FAST CMOS

12-BIT SYNCHRONOUS

BUS EXCHANGER

Integrated Device Technology, Inc.

FEATURES:

• 0.5 MICRON CMOS Technology

• 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)

• Packagesinclude25milpitchSSOP, 19.6milpitchTSSOP,

15.7 mil pitch TVSOP and 25 mil pitch Cerpack

• Extended commercial range of -40°C to +85°C

multiplexers for use in synchronous memory interleaving

applications. All registers have a common clock and use a

clock enable (CExxx) on each data register to control data

sequencing. The output enables and mux select (OEA, OEB

and SEL) are also under synchronous control allowing direc-

tion changes to be edge triggered events.

Thetri-portbusexchangerhasthree12-bitports. Datamay

be transferred between the A port and either/both of the B

ports. The clock enable (CE1B, CE2B, CEA1B and CEA2B)

inputs control the data storage. Both B ports have a common

output enable (OEB) to aid in synchronously loading the B

registers from the B port.

• Balanced Output Drivers:

±24mA (commercial)

±16mA (military)

• Reduced system switching noise

The FCT162H272AT/CT/ET have balanced output drive

with current limiting resistors. This offers low ground bounce,

minimal undershoot, and controlled output fall times-reducing

the need for external series terminating resistors.

• Typical VOLP (Output Ground Bounce) < 0.6V at

VCC = 5V, TA = 25°C

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

• Eliminates the need for external pull up resistors

The FCT162H272AT/CT/ET have "Bus Hold" which re-

tains 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.

DESCRIPTION:

The FCT162H272AT/CT/ET synchronous tri-port bus ex-

changers are high-speed, bidirectional,12-bit, registered, bus
