tc74vhc299f/ft 2007-10-01 1 toshiba cmos digital integrat ed ci rcuit silicon monolithic tc74vhc299f,tc74vhc299ft 8-bit pipo shift register with asynchronous clear the tc74vhc299 is an advanced high speed cmos 8-bit pipo shift register fabricat ed with silicon gate c 2 mos technology. it achieves the high speed op eration similar to equivalent bipolar schottky ttl while main taining the cmos low power dissipation. it has a four modes (hold, shift left, shift right and load data) controlled by the two selection inputs (s0, s1). when one or both enable ( 1g , 2g ) are high, the eight i/o are forced to the high-impedance state; however, sequential operation or clearing of th e register is not affected. all inputs are equipped with prot ection circuits against static discharge. features (note 1) (note 2) (note 3) ? high speed: f max = 160 mhz (typ.) at v cc = 5 v ? low power dissipation: i cc = 4 a (max) at ta = 25c ? high noise immunity: v nih = v nil = 28% v cc (min) ? balanced propagation delays: t plh ? t phl ? wide operating voltage range: v cc (opr) = 2 to 5.5 v ? low noise: v olp = 1.4 v (max) ? pin and function compatible with 74als299 note 1: do not apply a signal to a/qa to h/qh bus te rminal when it is in the output mode. damage may result. note 2: all floating (high impedance) a/qa to h/qh bus termi nals must have their input levels fixed by means of pull up or pull down resistors. note 3: a parasitic diode is formed between a/qa to h/qh bus and v cc terminals. therefore bus terminal can not be used to interface 5 v to 3 v systems directly. tc74vhc299f tc74vhc299ft weight sop20-p-300-1.27a : 0.22 g (typ.) tssop20-p-0044-0.65a : 0.08 g (typ.)
