The SN74BCT373N is an IC component from the 74 series of logic devices, specifically belonging to the BCT subfamily. It is an octal transparent latch with D-type flip-flop functionality, making it suitable for use in various digital systems. The IC is packaged in a 20-pin DIP (Dual Inline Package) and operates on a supply voltage ranging from 4.5V to 5.5V.
Key Features:
1. Octal Latching: The SN74BCT373N consists of eight latches that can store data on each of the individual flip-flops. These latches provide 8-bit parallel storage and output capabilities.
2. Transparent Operation: The IC features a transparent latch design, meaning the inputs are directly propagated to the outputs when the latch enable (LE) input is high. This enables real-time data transfers, as long as LE remains high.
3. D-type Flip-Flop: Each latch within the IC also operates as a D-type flip-flop. When the LE input is low, the latch retains the stored data, making it suitable for applications that necessitate holding data temporarily.
4. 3-state Outputs: The outputs of the SN74BCT373N can be tristated using the output enable (OE) control input. When OE is low, the outputs are active and reflect the stored latch data. Conversely, setting OE high places the outputs in the high impedance state
