FAST CMOS 18-BIT

R/W BUFFER

FEATURES:

DESCRIPTION:

• 0.5 MICRON CMOS Technology

The FCT162701T/AT is an 18-bit Read/Write buffer with

a four deep FIFO and a read-back latch. It can be used as

a read/write buffer between a CPU and memory or to

interface a high-speed bus and a slow peripheral. The A-

to-B (write) path has a four deep FIFO for pipelined opera-

• 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, tions. The FIFO can be reset and a FIFO full condition is

15.7 mil pitch TVSOP and 25 mil pitch Cerpack

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

indicated by the full flag (FF). The B-to-A (read) path has a

latch. A HIGH on LE, allows data to flow transparently from

B-to-A. A LOW on LE allows the data to be latched on the

falling edge of LE.

• Balanced Output Drivers:

±24mA (commercial),

±16mA (military)

• Reduced system switching noise

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

VCC = 5V, TA = 25°C

The FCT162701T/AT has a balanced output drive with

series termination. This provides low ground bounce,

minimal undershoot and controlled output edge rates.

• Ideal for new generation x86 write-back cache solutions

• Suitable for modular x86 architectures

• Four deep write FIFO

• Latch in read path

• Synchronous FIFO reset
