74HC194/74HCT194 4-Bit Bidirectional Universal Shift Register

A versatile shift register with synchronous operation and multiple data transfer modes.

  • Supply Voltage (VCC): 2.0V to 6.0V
  • CMOS Low Power Dissipation
  • High Noise Immunity
  • Latch-up Performance: Exceeds 100 mA per JESD 78 Class II Level B

Features:

  • Wide supply voltage range from 2.0V to 6.0V
  • CMOS low power dissipation
  • High noise immunity
  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

The 74HC194/74HCT194 is a 4-bit bidirectional universal shift register. The synchronous operation of the device is determined by the mode select inputs (S0, S1). In parallel load mode (S0 and S1 HIGH) data appearing on the D0 to D3 inputs, when S0 and S1 are HIGH, is transferred to the Q0 to Q3 outputs. When S0 is HIGH and S1 is LOW data is entered serially via DSL and shifted from left to right; when S0 is LOW and S1 is HIGH data is entered serially via DSR and shifted from right to left. DSR and DSL allow multistage shift right or shift left data transfers without interfering with parallel load operation. If both S0 and S1 are LOW, existing data is retained in a hold mode. Mode select and data inputs are edge-triggered, responding only to the LOW-to-HIGH transition of the clock (CP). Therefore, the only timing restriction is that the mode control and selected data inputs must be stable one set-up time prior to the positive transition of the clock pulse. When LOW, the asynchronous master reset (MR) overrides all other input conditions and forces the Q outputs LOW. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Specifications:

  • Supply Voltage (VCC): 2.0V to 6.0V
  • DC Input or Output Voltage (VIN, VOUT): 0VccV
  • Ambient Temperature: -40°C to +125°C
  • Input Rise or Fall Times:
  • VCC = 2.0V: 625ns
  • VCC = 4.5V: 139ns
  • VCC = 6.0V: 83ns

Package Includes:

  • 1 X 74HC194 4-Bit Bi-directional Shift Register IC (74194 IC) DIP-16 Package
