0.5 MICRON CMOS Technology

Thisoctalpostiveedge-triggeredD-typeflip-flopisbuiltusingadvanced

dual metal CMOS technology. The ALVCH374 device is particularly

suitableforimplementingbufferregisters,I/Oports,bidirectionalbusdrivers,

andworkingregisters.Onthepositivetransitionoftheclock(CLK)input,the

Qoutputs are settothe logiclevels atthe data (D)inputs.

Typical t (o) (Output Skew) < 250ps

ESD > 2000V per MIL-STD-883, Method 3015;

> 200V using machine model (C = 200pF, R = 0)

VCC = 3.3V ±0.3V, Normal Range

Drive Features for ALVCH374:

–

High Output Drivers: ±24mA

Suitable for heavy loads

The ALVCH374 has been designed with a ±24mA output driver. This

driver is capable of driving a moderate to heavy load while maintaining

speedperformance.

APPLICATIONS:

• 3.3V High Speed Systems

• 3.3Vandlowervoltagecomputingsystems

The ALVCH374 has a “bus-hold” which retains the inputs’ last state

wheneverthe inputbus goes toa highimpedance.This prevents floating

inputs andeliminates the needforpull-up/downresistors.
