M74HC595B1R Datasheet

Counter Shift Registers


The M74HC595B1R device is a high speed CMOS 8-bit shift register with output latches (3-state) fabricated with silicon gate C2MOS technology.This device contains an 8-bit serial in, parallel out shift register that feeds an 8-bit D-type storage register. The storage register has 8 3-state outputs. Separate clocks are provided for both the shift register and the storage register. M74HC595B1R Features • High speed: fMAX= 59 MHz (typ.) at VCC= 6 V• Low power dissipation: ICC= 4 μA (max.) at TA= 25 °C• High noise immunity: VNIH= VNIL= 28% VCC(min.)• Symmetrical output impedance:|IOH| = IOL= 6 mA (min.) for QA to QH|IOH| = IOL= 4 mA (min.) for QH’• Balanced propagation delays: tPLH≅ tPHL• Wide operating voltage range: VCC(opr.) = 2 V to 6 V• Pin and function compatible with 74 series 595
