Overview

The MC74VHC595 is an advanced high speed 8-bit shift register with an output storage register fabricated with silicon gate CMOS technology.

It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.

The MC74VHC595 contains an 8-bit static shift register which feeds an 8-bit storage register.

Shift operation is accomplished on the positive going transition of the Shift Clock input (SCK). The output register is loaded with the contents of the shift register on the positive going transition of the Register Clock input (RCK). Since the RCK and SCK signals are independent, parallel outputs can be held stable during the shift operation. And, since the parallel outputs are 3-state, the VHC595 can be directly connected to an 8-bit bus. This register can be used in serial-to-parallel conversion, data receivers, etc.

The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The inputs tolerate voltages up to 7V, allowing the interface of 5V systems to 3V systems.

  • General applications include: Serial-to-parallel data conversion.

  • Some end product applications include: computer, personal equipment, office equipment, measuring equipment, industrial robotics, domestic appliances

  • High Speed: fmax = 185MHz (Typ) at VCC = 5V
  • Low Power Dissipation: ICC = 4mA (Max) at TA = 25°C
  • High Noise Immunity: VNIH = VNIL = 28% VCC
  • Power Down Protection Provided on Inputs
  • Balanced Propagation Delays
  • Designed for 2V to 5.5V Operating Range
  • Low Noise: VOLP = 1.0V (Max)
  • Pin and Function Compatible with Other Standard Logic Families
  • Latchup Performance Exceeds 300mA
  • ESD Performance: HBM > 2000V; Machine Model > 200V
  • These are Pb-Free Devices

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
