1 / 14 page ©1995 Fairchild Semiconductor Corporation www.fairchildsemi.com 74LCX74 Rev. 1.7.0 March 2008 74LCX74 Low Voltage Dual D-Type Positive Edge-Triggered Flip-Flop with 5V Tolerant Inputs Features ■ 5V tolerant inputs ■ 2.3V–3.6V VCC specifications provided ■ 7.0ns tPD max. (VCC = 3.3V), 10µA ICC max. ■ Power down high impedance inputs and outputs ■ ±24mA output drive (VCC = 3.0V) ■ ■ Latch-up performance exceeds JEDEC 78 conditions ■ ESD performance: – Human body model > 2000V – Machine model > 200V ■ Leadless Pb-Free DQFN package General Description The LCX74 is a dual D-type flip-flop with Asynchronous Clear and Set inputs and complementary (Q, Q) outputs. Information at the input is transferred to the outputs on the positive edge of the clock pulse. After the Clock Pulse input threshold voltage has been passed, the Data input is locked out and information present will not be transferred to the outputs until the next rising edge of the Clock Pulse input. Asynchronous Inputs: ■ LOW input to SD (Set) sets Q to HIGH level ■ LOW input to CD (Clear) sets Q to LOW level ■ Clear and Set are independent of clock ■ Simultaneous LOW on CD and SD makes both Q and Q HIGH Ordering Information Note: 1. DQFN package available in Tape and Reel only. Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number. All packages are lead free per JEDEC: J-STD-020B standard.
