Features
1. Octal Latch: It can store eight bits of data, making it suitable for parallel data storage.
2. Transparent Mode: Data present at the inputs (D) is passed to the outputs (Q) when the latch is enabled (LE high).
3. Control Inputs: It includes a latch enable (LE) and an output enable (OE) pin for controlling data flow.
4. TTL Compatible: The device is compatible with TTL (Transistor-Transistor Logic) levels.
5. High Speed: Operating at speeds up to 25 ns for fast data processing.
6. Power Supply: Typically operates on a 5V power supply.
7. Temperature Range: Military-grade version (SN54) supports extended temperature ranges.
8. Package Type: Available in a 20-pin dual in-line package (DIP).
This device is ideal for applications requiring temporary data storage and controlling data flow in digital systems.
Pinout
Pin Count: 20 pins
Functions:
- Data Inputs (D0-D7): Pins 2-9 receive the input data.
- Latch Enable (LE): Pin 1 enables the latch; when high, data is transferred from the inputs to the outputs.
- Output Enable (OE): Pin 10 controls the output; when low, the outputs are enabled; when high, the outputs are in a high-impedance state.
- Outputs (Q0-Q7): Pins 11-18 provide the latched output data.
- Ground (GND): Pin 19 connects to ground.
- VCC: Pin 20 connects to the positive supply voltage (typically +5V).
The device is useful for temporary storage and data manipulation in various digital applications.
