The Texas Instruments 74LS166 is an 8-bit shift register featuring parallel-in or serial-in and serial-out functionality. This device is part of the LS TTL family and is designed with buffered inputs for reduced drive requirements. It supports synchronous loading and has a direct overriding clear input.
The 74LS166 operates with a supply voltage range of 4.75V to 5.25V and has a typical clock speed of 25ns. It is suitable for parallel to serial conversion tasks. The component is housed in a 16-SOIC surface mount package.
Key features include gated clock inputs and an overriding clear input. The shift/load input determines the mode of operation, enabling serial data input and coupling of flip-flops for serial shifting when high. When low, synchronous loading occurs with parallel data inputs enabled, inhibiting serial data flow.
This shift register is clocked on the low-to-high edge of the clock pulse. One clock input can function as a clock enable or inhibit. The device is designed to minimize switching transients through input clamping diodes, simplifying system design.
