IDT54/74FCT374T/AT/CT FAST CMOS OCTAL D REGISTER (3-STATE) MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS OCTAL D IDT54/74FCT374T/AT/CT REGISTER (3-STATE) FEATURES: DESCRIPTION: Std., A, and C grades The FCT374T is an 8-bit register built using an advanced dual metal Low input and output leakage 1A (max.) CMOS technology. These registers consist of eight D-type flip-flops with a CMOS power levels buffered common clock and buffered 3-state output control. When the output True TTL input and output compatibility: enable (OE) input is low, the eight outputs are enabled. When the OE input VOH = 3.3V (typ.) is high, the outputs are in the high-impedance state. VOL = 0.3V (typ.) Input data meeting the set-up and hold time requirements of the D inputs High Drive outputs (-15mA IOH, 48mA IOL) is transferred to the Q outputs on the low-to-high transition of the clock input. 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 permitlive insertio Available in the following packages: Industrial: SOIC, SSOP, QSOP Military: CERDIP, LCC FUNCTIONAL BLOCK DIAGRAM D0 D1 D2 D3 D4 D5 D6 D7 CP D D D D D D D D CP CP CP CP CP CP CP CP Q QQQ Q QQ Q OE Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
