the mc74vhc595 is an advanced high speed 8bit shift register with an output storage register fabricated with silicon gate cmos technology. it achieves high speed operation similar to equivalent bipolar schottky ttl while maintaining cmos low power dissipation. the mc74vhc595 contains an 8bit static shift register which feeds an 8bit storage register. shift operation is accomplished on the positive going transition of the shift clock input (sck). the output register is loaded with the contents of the shift register on the positive going transition of the register clock input (rck). since the rck and sck signals are independent, parallel outputs can be held stable during the shift operation. and, since the parallel outputs are 3state, the vhc595 can be directly connected to an 8bit bus. this register can be used in serialtoparallel conversion, data receivers, etc. the internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. the inputs tolerate voltages up to 7v, allowing the interface of 5v systems to 3v systems. ? high speed: f max = 185mhz (typ) at v cc = 5v ? low power dissipation: i cc = 4 m a (max) at t a = 25 c ? high noise immunity: v nih = v nil = 28% v cc ? power down protection provided on inputs ? balanced propagation delays ? designed for 2v to 5.5v operating range ? low noise: v olp = 1.0v (max) ? pin and function compatible with other standard logic families ? latchup performance exceeds 300ma ? esd performance: hbm > 2000v; machine model > 200v pin assignment 13 14 15 16 9 10 11 12 5 4 3 2 1 8 7 6 rck oe si qa vcc sqh sclr sck qe qd qc qb gnd qh qg qf http://onsemi.com device package shipping ordering information mc74vhc595d soic16 48 units/rail mc74vhc595dr2 soic16 2500 units/reel soic16 d suffix case 751b tssop16 dt suffix case 948f soic eiaj16 m suffix case 966 marking diagrams 1 8 9 16 1 8 16 9 1 16 9 8 vhc595 awlyyww a = assembly location wl = wafer lot yy = year ww = work week vhc 595 awlyww vhc595 alyw mc74vhc595dt tssop16 96 units/rail mc74vhc595dtr2 tssop16 2500 units/reel mc74vhc595m soic eiaj16 50 units/rail mc74vhc595mel soic eiaj16 2000 units/reel a = assembly location l = wafer lot y = year w = work week a = assembly location wl = wafer lot y = year ww = work week mc74vhc595dtel tssop16 2000 units/reel
