M54HC165 m74hc165 september 1993 8 bit piso shift register b1r (plastic package) order codes : M54HC165f1r m74hc165m1r m74hc165b1r m74hc165c1r f1r (ceramic package) m1r (micro package) c1r (chip carrier) pin connections (top view) nc = no internal connection . high speed t pd = 15 ns (typ.) at v cc =5v . low power dissipation i cc =4 m a (max.) at t a =25 c . output drive capability 10 lsttl loads . balanced propagation delays t plh =t phl . symmetrical output impedance i ol = ? i oh ? = 4 ma (min.) . high noise immunity v nih =v nil =28%v cc (min.) . wide operating voltage range v cc (opr) = 2 v to 6 v . pin and function compatible with 54/74ls165 description the m54/74hc165 is a high speed cmos 8 bit piso shift register fabricated in silicon gate c 2 mos technology. it has the same high speed performance of lsttl combined with true cmos low power consumption. it achives the high speed operation similar to equivalent lsttl while maintaining the cmos low power dissipation. this device contains eight clocked master slave rs flip-flops connected as a shift register, with auxiliary gating to provide over-riding asynchronous parallel entry. parallel data entres when the shift/load input is low. the parallel data can change while shift/load is low, provided that the recommended set-up and hold times are observed. for clocked operation, shift/load must be high. the two clock input perform identically; one can be used as a clock inhibit by applying a high signal; to permit this operation clocking is accomplished through a 2 input nor gate. to avoid double clocking, however, the inhibit signal should only go high while the clock is high. otherwise the rising inhibit signal will cause the same response as rising clock edge. all inputs are equipped with protection circuits against static discharge and transient excess voltage. 1/13
