The SN74ALS805AN3 is an integrated circuit (IC) component designed and manufactured by Texas Instruments. It belongs to the SN74ALS series and is a part of the ALS (Advanced Low-Power Schottky) family. This IC is a dual 4-bit D-type latch that offers high-speed, low-power logic functions.
Key features of the SN74ALS805AN3 include:
1. Dual 4-bit D-Type Latch: The IC consists of two separate D-type latch blocks, each capable of storing and outputting 4 bits of data. This makes it suitable for applications requiring storage and retrieval of small data sets.
2. Schottky Technology: The ALS805AN3 incorporates advanced low-power Schottky TTL technology that ensures high-performance operation with reduced power consumption. The Schottky diode structure results in faster switching speeds and higher noise immunity compared to regular TTL.
3. Active-Low Enable Inputs: Each latch block in the IC contains an active-low enable (G) input. When the enable input is low, the data at the D input is latched and transferred to the outputs. Controlling the enable input allows for efficient data storage and retrieval.
4. Buffered Outputs: The SN74ALS805AN3 provides buffered outputs (Q and Q?) for each latch block, which ensures proper signal propagation and avoids any external interference or loading effects
