The SN74ALS166D from Texas Instruments is a parallel-load, 8-bit serial shift register. It is compatible with most TTL logic families and features buffered inputs to reduce drive requirements. Input clamping diodes help minimize switching transients.
This shift register supports parallel-in or serial-in modes, controlled by the shift/load (SH/LD) input. When SH/LD is high, it enables serial data input for shifting. When low, it enables parallel data inputs (A-H) for synchronous loading on the next clock pulse. Clocking occurs on the low-to-high edge of the clock pulse, with gated clock inputs (CLK and CLK INH) allowing for clock-enable functionality.
The device operates over a temperature range of 0°C to 70°C and supports a clock frequency of up to 45 MHz. It is available in a 16-SOIC package and is suitable for surface mounting.
Key electrical characteristics include a supply voltage range of 4.5V to 5.5V, a maximum output current (IOL) of 8mA, and a maximum output current (IOH) of -0.4mA. The maximum supply current is 24mA.
