OCTAL D FLIP-FLOP
WITH MASTER RESET
DESCRIPTION:
FEATURES:
The FCT273T is an octal D flip-flop built using an advanced dual metal
CMOS technology. The FCT273T has eight edge-triggered D-type flip-
flops with individual D inputs and O outputs. The common buffered Clock
(CP) and Master Reset (MR) inputs load and reset (clear) all flip-flops
simultaneously.
• Std., A, and C grades
• Low input and output leakage ≤1µA (max.)
• CMOS power levels
• True TTL input and output compatibility:
– VOH = 3.3V (typ.)
The register is fully edge-triggered. The state of each D input, one set-
up time before the low-to-high clock transition, is transferred to the corre-
spondingflip-flop’sOoutput.
All outputs will be forced low independently of Clock or Data inputs by
a low voltage level on the MR input. The device is useful for applications
where the true output only is required and the Clock and Master Reset are
commontoallstorageelements.
– VOL = 0.3V (typ.)
• High Drive outputs (-15mA IOH, 48mA IOL)
• Meets or exceeds JEDEC standard 18 specifications
• Military product compliant to MIL-STD-883, Class B and DESC
listed (dual marked)
• Power off disable outputs permit "live insertion"
• Available in the following packages:
– Industrial: SOIC, SSOP, QSOP
– Military: CERDIP, LCC
