Description

The SN74HCT373N is an 8-bit transparent D-type latch with 3-state outputs, part of the 74HCT series from Texas Instruments. This integrated circuit is designed for high-speed applications and operates within a voltage range of 4.5V to 5.5V. It features a transparent latch function where data at the input is transferred to the output when the latch-enable (LE) input is high. When LE is low, the last data present at the input before LE transitioned low is retained at the output.
The device also includes a 3-state output control, allowing for easy connection to shared buses. When the output-enable (OE) input is high, the outputs are in the high-impedance state, effectively disconnecting them from the bus, and when OE is low, the outputs reflect the latch's state.
The SN74HCT373N is designed to be pin-compatible with the older 74HC series, making it a versatile choice for upgrades in existing systems. It is commonly used in digital systems where data storage and retrieval with controlled output is necessary.

Pinout

The SN74HCT373N is a type of octal D-type transparent latch with three-state outputs, typically used in digital circuits. It has 20 pins. Here is a concise breakdown of its pin functions:
1. Pin 1 (OE̅): Output Enable, active low. When low, the outputs are enabled; when high, the outputs are in a high-impedance state.
2. Pin 2-9 (Q0-Q7): These are the data output pins. They output the stored data when the latch is enabled.
3. Pin 10 (GND): Ground connection.
4. Pin 11-18 (D0-D7): Data inputs. These accept the input data that will be latched.
5. Pin 19 (LE): Latch Enable. When high, the latch is transparent and allows data to flow from input to output; when low, the data is latched.
6. Pin 20 (VCC): Supply voltage.
The device is used in applications where data needs to be stored temporarily and transferred between registers, commonly in microprocessor and computer systems.
