Philips 74LV595
The 74LV595 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC/HCT595. The shift register and storage register have separate clocks. The data in each register is transferred to the storage register on a positive-going transition of the STCP input.FEATURES
● Optimized for Low Voltage applications: 1.0V to 3.6V● Accepts TTL input levels between VCC = 2.7V and VCC = 3.6V
● Typical VOLP (output ground bounce) < 0.8V at VCC = 3.3V,
● Typical VOHV (output VOH undershoot) > 2V at VCC = 3.3V,
● 8-bit serial input
● 8-bit serial or parallel output
● Storage register with 3-State outputs
● Shift register with direct clear
● Output capability: – parallel outputs; bus driver – serial output; standard Tamb = 25°C Tamb = 25°C
APPLICATIONS
● Serial-to-parallel data conversion● Remote control holding register
DESCRIPTION
The74LV595 is an 8-stage serial shift register with a storage register and 3-State outputs. Data is shifted on the positive-going transitions of the SHCP 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’) all for cascading. It is also provided with asynchronous reset (active LOW) for all 8 shift register stages.
