74HC595; 74HCT595
The 74HC/HCT595 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT595 is an 8-stage serial shift register with a storage register and 3-state outputs. The shift register and storage register have separate clocks. Data is shifted on the positive-going transitions of the SH_CP input. The data in each register is transferred to the storage register on a positive-going transition of the ST_CP input. If both clocks are connected together, the shift register will always be one clock pulse ahead of the storage register. The shift register has a serial input (DS) and a serial standard output (Q7') for cascading. It is also provided with asynchronous reset (active LOW) for all 8 shift register stages. The storage register has 8 parallel 3-state bus driver outputs. Data in the storage register appears at the output whenever the output enable input (OE) is LOW.
QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns. TYPICAL SYMBOL tPHL/tPLH PARAMETER propagation delay SH_CP to Q7' SH_CP to Qn MR to Q7' fmax CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW). PD = CPD × VCC2 × fi × N + (CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = total load switching outputs; (CL × VCC2 × fo) = sum of the outputs. 2. For 74HC595 the condition is VI = GND to VCC. For 74HCT595 the condition is VI = GND to VCC - 1.5 V. 2003 Jun 25 2 maximum clock frequency SH_CP and ST_CP input capacitance power dissipation capacitance per package notes 1 and 2 CONDITIONS 74HC CL = 50 pF; VCC = 4.5 V 19 20 100 100 3.5 115 25 24 52 57 3.5 130 ns ns ns MHz pF pF 74HCT UNIT
