SN74ACT373DB

The SN74ACT373DB is an octal transparent D-type latch with 3-state outputs, part of the 74ACT series of high-speed CMOS logic ICs. It is designed for use in applications requiring high-speed data latching, buffering, and driving. This device features eight latches, which are edge-triggered and controlled by a latch enable (LE) input and an output enable (OE) input. When LE is high, the latches become transparent, allowing data at the input to flow through to the output. When LE is low, the data is latched, and the output remains constant regardless of input changes.
The 3-state output feature is controlled by the OE input, which, when high, places the outputs in a high-impedance state, effectively disconnecting them from the circuit and allowing for bus-oriented applications. The SN74ACT373DB operates on a supply voltage of 4.5V to 5.5V and is capable of driving up to 24mA output current. It is available in a small-outline package (SOP), making it suitable for space-constrained applications. This device is widely used in digital systems for data storage, interfacing, and control tasks.

The SN74ACT373DB is an octal transparent D-type latch with 3-state outputs. It has a total of 20 pins. Here's a brief overview of its pin functions:
1. Pin 1 (OE): Output Enable, active low
2. Pin 11 (LE): Latch Enable
3. Pins 2-9 (D0-D7): Data inputs
4. Pins 12-19 (Q0-Q7): 3-state latch outputs
5. Pin 10 (GND): Ground
6. Pin 20 (VCC): Supply Voltage
The device operates with a supply voltage range of 4.5V to 5.5V. The SN74ACT373 latches the data present at the inputs when the Latch Enable (LE) pin is high, and data is transparent to outputs. When LE goes low, the latched state is retained. The Output Enable (OE) pin controls the output buffer; when low, the outputs follow the latch state, and when high, the outputs are in a high-impedance state, effectively disconnecting them from the circuit. This makes the SN74ACT373DB suitable for bus interface applications.
