The DM74LS166N from Texas Instruments is an 8-bit shift register designed for parallel-in or serial-in, serial-out data transfer. This device features gated clock inputs and an overriding clear input for flexible control. All inputs are buffered to reduce drive requirements, and input clamping diodes help minimize switching transients.
The shift register operates with a supply voltage range of 4.75V to 5.25V, with a nominal value of 5V. It supports a clock frequency of up to 25MHz. Key timing parameters include a setup time of 30ns for mode control and 20ns for data, and a hold time of 0ns. The operating temperature range is from 0°C to 70°C.
Data loading can be synchronous via parallel inputs when the shift/load input is low, or serial shifting occurs when it is high. The clocking mechanism allows for clock-enable or clock-inhibit functions. The device is available in N16A and M16B package types.
