Description
The 74HC194 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.
Features
- Wide supply voltage range from 2.0 V to 6.0 V.
- CMOS low power dissipation.
- High noise immunity.
- Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.
- Complies with JEDEC standards:.
- JESD8C (2.7 V to 3.6 V).
- JESD7A (2.0 V to 6.0 V).
- CMOS input levels.
- Shift-left and shift right capability.
- Synchronous parallel and serial data transfer.
- Easily expanded for both serial and parallel operat.
