7475 IC 4-bit Bi-stable Latch DIP-16
The 7475 IC 4-bit Bi-stable Latch DIP-16 is a high-performance Transistor-Transistor Logic (TTL) device designed to act as a temporary storage element for digital information. This integrated circuit contains four separate transparent latches, making it suitable for applications requiring the momentary storage and control of 4-bit binary data. The device is configured in a standard 16-pin Dual In-line Package (DIP) and operates reliably from a single power supply.
Features:
- Contains four independent bi-stable transparent latches within a single package.
- Features two separate enable (strobe) inputs for independent control of two 2-bit latch groups.
- Provides complementary outputs (Q and Q-bar) for each of the four latches.
- Operates on a standard single 5V power supply.
