tc74lvx273f/fw/ft 2002-01-16 1 toshiba cmos digital integrated circuit silicon monolithic tc74lvx273f,TC74LVX273FW,tc74lvx273ft octal d-type flip-flop with clear the tc74lvx273f/ fw/ ft is a high-speed cmos octal d-flip flop fabricated with silicon gate cmos technology. designed for use in 3-v systems, it achieves high-speed operation while maintaining the cmos low power dissipation. this device is suitable for low-voltage and battery operated systems. information signals applied to d inputs are transferred to the q outputs on the positive going edge of the clock pulse. when the clr input is held low, the q outputs are in the low logic level independent of the other inputs. an input protection circuit ensures that 0 to 5.5v can be applied to the input pins without regard to the supply voltage. this device can be used to interface 5v to 3v systems and two supply systems such as battery back up. this circuit prevents device destruction due to mismatched supply and input voltages. features high-speed: f max = 150 mhz (typ.) (v cc = 3 v) low power dissipation: i cc = 4 a (max) (ta = 25c) input voltage level: v il = 0.8 v (max) (v cc = 3 v) v ih = 2.0 v (min) (v cc = 3 v) power-down protection provided on all inputs balanced propagation delays: t plh t phl low niose: v olp = 0.8 v (max) pin and function compatible with 74hc273 note: xxxf (jedec sop) is not available in japan. tc74lvx273f TC74LVX273FW tc74lvx273ft weight sop20-p-300-1.27: 0.22 g (typ.) sol20-p-300-1.27: 0.46 g (typ.) tssop20-p-0044-0.65: 0.08 g (typ.)
