TD74BC574p/f 2002-07-11 1 toshiba bi-cmos digital integrated circuit silicon monolithic TD74BC574p,TD74BC574f octal d-type flip-flop with 3-state outputs (non-inverted) the TD74BC574p/TD74BC574f is a high-speed 8-bit flip-flop fabricated with silicon gate bi-cmos technology. it achieves the high-speed operation equivalent to the fast family while maintaining the bi-cmos low-power dissipation. the TD74BC574p/f is a non-inverting flip-flop. each bit is individually controlled by a clock input (ck) and an output enable input (oe). when the oe input is high, all eight outputs are in the high-impedance state, which facilitates the interface with bus lines. all inputs are equipped with resistors and diodes to protect against electrostatic discharge (esd). features high-speed operation ........................ t pd = 8.8 ns (typ.) symmetrical output impedance ....... i oh = ? 3 ma (max) i ol = 24 ma (max) low power dissipation ...................... i ccd = 7 ma (typ.) i ccz = 1 0 a (typ.) operating temperature range .......... ta = ? 40c to 85c high esd protection ......................... 2000 v (mil standard) pin and function compatible with fast (74f574) logic diagram TD74BC574p TD74BC574f weight dip20-p-300-2.54a : 1.48 g (typ.) sop20-p-300-1.27 : 0.25 g (typ.) ck oe q1 1 11 2 19 q2 3 18 q3 4 17 q4 5 16 q5 6 15 q6 7 14 q7 8 13 ck q d ck q d ck q d ck q d ck q d ck q d ck q d d1 d2 d3 d4 d5 d6 d7 9 12 ck q d q0 d0 ( datasheet : )
