The SN74ALS666NT from Texas Instruments is an 8-bit D-type transparent latch featuring 3-state outputs and read-back functionality. This device is designed for efficient storage of input data bus contents and allows for reading the stored data back onto the bus.
Key electrical characteristics include an operating voltage range of 4.5V to 5.5V and a propagation delay of 6ns. The output current is rated at 400µA for high output and 8mA for low output. It operates reliably within a temperature range of 0°C to 70°C.
Designed for bus-structured applications, the SN74ALS666NT utilizes a bus-structured pinout. The latch enable (LE) input controls data flow, while output enable (OE1, OE2) inputs manage the 3-state buffer output. A read-back control (OERB) input allows data from the latch output to be passed back to the input data bus.
This component is available in a 24-pin Dual In-line Package (DIP) with a standard 0.300-inch lead spacing, suitable for through-hole mounting. The logic type is a D-Type Transparent Latch, with one independent circuit configured as 8:8.
