7475 IC 4-bit Bi-stable Latch DIP-16

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. Specifications: Parameter Value Component Type 4-Bit Bi-stable Latch Logic Family TTL Supply Voltage Range (VCC) 4.75V to 5.25V Nominal Supply Voltage 5V Output Type Complementary Q and Q-bar Number of Latches 4 Enable Control 2 Separate 2-Bit Enables Max Propagation Delay (Strobe to Q) 35ns Max Supply Current (ICC) 40mA Operating Temperature (TA) 0°C~70°C Package Type 16-PinDIP Pin Configuration: Pin Number Description 1 Complement Q1 Output 2 D1 Input 3 D2 Input 4 Enable 3/4 5 Vcc – Positive Power Supply 6 D3 Input 7 D4 Input 8 Complement Q4 Output 9 Q4 Output 10 Q3 Ouput 11 Complement Q3 Output 12 Gnd – Ground 13 Enable 1/2 14 Complement Q2 Output 15 Q2 Output 16 Q1 Output Applications: Temporary storage of digital data in microcomputer and peripheral interfacing.
