74ACTQ16374

16-Bit D-Type Flip-Flop with 3-STATE Outputs

General Description

The ACTQ16374 contains sixteen non-inverting D-type flip-

flops with 3-STATE outputs and is intended for bus oriented

applications. The device is byte controlled. A buffered clock

(CP) and Output Enable (OE) are common to each byte

and can be shorted together for full 16-bit operation.

The ACTQ16245 utilizes Fairchild Quiet Series

¥ technol-

ogy to guarantee quiet output switching and improved

dynamic threshold performance. FACT Quiet Series

¥ fea-

tures GTO

¥ output control for superior performance.

Features

s Utilizes Fairchild FACT Quiet Series technology

s Guaranteed simultaneous switching noise level and

dynamic threshold performance

s Guaranteed pin-to-pin output skew

s Buffered Positive edge-triggered clock

s Separate control logic for each byte

s 16-bit version of the ACTQ374

s Outputs source/sink 24 mA

s Additional specs for Multiple Output Switching

s Output loadings specs for both 50 pF and 250 pF loads

Ordering Code:

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
