  74vhc74 ?dual d-type flip-flop with preset and clear ?992 fairchild semiconductor corporation www.fairchildsemi.com 74vhc74 rev. 1.3.0 f ebruary 2008 74vhc74 dual d-type flip-flop with preset and clear features high speed: f max = 170mhz (typ.) at t a = 25? high noise immunity: v nih = v nil = 28% v cc (min.) power down protection is provided on all inputs low power dissipation: i cc = 2? (max.) at t a = 25? pin and function compatible with 74hc74 general description the vhc74 is an advanced high speed cmos dual d-type flip-flop fabricated with silicon gate cmos technology. it achieves the high speed operation similar to equivalent bipolar schottky ttl while maintaining the cmos low power dissipation. the signal level applied to the d input is transferred to the q output during the posi- tive going transition of the ck pulse. clr and pr are independent of the ck and are accomplished by setting the appropriate input low. an input protection circuit ensures that 0v to 7v 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 backup. this circuit prevents device destruction due to mismatched supply and input voltages. ordering information device also available in tape and reel. specify by appending suffix letter ??to the ordering number. all packages are lead free per jedec: j-std-020b standard. order number package number package description 74vhc74m m14a 14-lead small outline integrated circuit (soic), jedec ms-012, 0.150" narrow 74vhc74sj m14d 14-lead small outline package (sop), eiaj type ii, 5.3mm wide 74vhc74mtc mtc14 14-lead thin shrink small outline package (tssop), jedec mo-153, 4.4mm wide 74vhc74n n14a 14-lead plastic dual-in-line package (pdip), jedec ms-001, 0.300" wide
