They are specified in compliance with JEDEC standard no. 7A.The 74HC/HCT165 are 8-bit parallel-load or serial-in shift registers with complementary serial outputs (Q 7and Q 7)available from the last stage. When the parallel load (PL)input is LOW, parallel data from the D 0toD 7inputs are loaded into the register asynchronously.When PL is HIGH, data enters the register serially at the D s input and shifts one place to the right(Q 0→Q 1→Q 2,etc.) with each positive-going clock transition. This feature allows parallel-to-serial converterexpansion by tying the Q 7output to the D S input of the succeeding stage.The clock input is a gated-OR structure which allows one input to be used as an active LOW clock enable (CE)input.The pin assignment for the CP and CE inputs is arbitrary and can be reversed for layout convenience. The LOW-to-HIGH transition of input CE should only take place while CP HIGH for predictable operation. Either the CP or the CE should be HIGH before the LOW-to-HIGH transition of PL to prevent shifting the data when PL is activated.APPLICATIONSParallel-to-serial data conversionQUICK REFERENCE DATAGND = 0 V; T amb = 25°C; t r = t f = 6 ns Notes1.C PD is used to determine the dynamic power dissipation (P D in μW):P D = C PD ×V CC 2×f i +∑(C L ×V CC 2×f o )where:f i = input frequency in MHz f o = output frequency in MHz ∑(C L ×V CC 2×f o )= sum of outputs C L =output load capacitance in pF V CC =supply voltage in V2.For HC the condition is V I = GND to V CCFor HCT the condition is V I = GND to V CC ?1.5 V ORDERING INFORMATIONSee “74HC/HCT/HCU/HCMOS Logic Package Information”.SYMBOL PARAMETERCONDITIONS TYPICAL UNITHCHCTt PHL / t PLHpropagation delay CP to Q 7,Q 7PL to Q 7,Q 7D 7 to Q 7,Q 7C L = 15 pF; V CC = 5 V161511141711ns ns ns f max maximum clock frequency 5648MHz C I input capacitance3.5 3.5pF C PD power dissipation capacitance per packagenotes 1 and 23535pFPIN DESCRIPTIONPIN NO.SYMBOL NAME AND FUNCTION1PL asynchronous parallel load input (active LOW)7Q7complementary output from the last stage9Q7serial output from the last stage2CP clock input (LOW-to-HIGH edge-triggered)8GND ground (0 V)10D s serial data input11, 12, 13, 14, 3, 4, 5, 6D0to D7parallel data inputs15CE clock enable input (active LOW)16V CC positive supply voltageFig.1 Pin configuration.Fig.2 Logic symbol.Fig.3 IEC logic symbol.FUNCTION TABLE Note1.H = HIGH voltage levelh = HIGH voltage level one set-up time prior to the LOW-to-HIGH clock transition L = LOW voltage levelI =LOW voltage level one set-up time prior to the LOW-to-HIGH clock transitionq =lower case letters indicate the state of the referenced output one set-up time prior to theLOW-to-HIGH clock transition X = don’t care↑=LOW-to-HIGH clock transitionOPERATING MODESINPUTS Q n REGISTERS OUTPUTS PLCECPD SD 0-D 7Q 0Q 1-Q 6Q 7Q 7parallel load L L X X X X X X L H L H L - L H - H L H H L serial shift H H L L ↑↑l h X X L H q 0-q 5q 0-q 5q 6q 6q 6q 6hold “do nothing”HH X X X q 0q 1-q 6q 7q 7Fig.4 Functional diagram.Fig.5 Logic diagram.DC CHARACTERISTICS FOR 74HCFor the DC characteristics see“74HC/HCT/HCU/HCMOS Logic Family Specifications”.
