Dual 4-bit serial-in/parallel-out shift register
FEATURES * Output capability: standard * ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT4015 are high-speed Si-gate CMOS devices and are pin compatible with the "4015" of the "4000B" series. They are specified in compliance with JEDEC standard no. 7A.
74HC/HCT4015
The 74HC/HCT4015 are dual edge-triggered 4-bit static shift registers (serial-to-parallel converters). Each shift register has a serial data input (1D and 2D), a clock input (1CP and 2CP), four fully buffered parallel outputs (1Q0 to 1Q3 and 2Q0 to 2Q3) and an overriding asynchronous master reset (1MR and 2MR). Information present on nD is shifted to the first register position, and all data in the register is shifted one position to the right on the LOW-to-HIGH transition of nCP. A HIGH on nMR clears the register and forces nQ0 to nQ3 to LOW, independent of nCP and nD.
QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C; tr = tf = 6 ns TYPICAL SYMBOL tPHL/ tPLH fmax CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in W): PD = CPD x VCC2 x fi + (CL x VCC2 x fo) where: fi = input frequency in MHz fo = output frequency in MHz (CL x VCC2 x fo) = sum of outputs CL = output load capacitance in pF VCC = supply voltage in V 2. For HC the condition is VI = GND to VCC For HCT the condition is VI = GND to VCC - 1.5 V ORDERING INFORMATION See "74HC/HCT/HCU/HCMOS Logic Package Information".
