Features
1. Quad Configuration: It contains four independent R/S (reset/set) latches.
2. 3-State Outputs: The outputs can be in one of three states: high, low, or high-impedance, allowing for easy bus interfacing.
3. Wide Supply Voltage Range: Operates from 3V to 15V, making it versatile for various applications.
4. Low Power Consumption: Due to CMOS technology, it consumes very little power.
5. High Noise Immunity: Provides robust performance even in noisy environments.
6. Latch-Up Performance: High latch-up immunity with a minimum current of 100mA.
7. Temperature Range: Suitable for operation in a range of conditions, typically -55°C to 125°C.
8. Input Protection: Built-in protection against electrostatic discharge.
9. TTL Compatibility: Compatible with TTL levels when operated under certain conditions.
These features make the CD4044BDR suitable for memory storage, sequential logic applications, and interfacing logics in digital systems.
Pinout
1. VDD (Pin 16): Power supply voltage.
2. VSS (Pin 8): Ground.
3. Qn (Pins 2, 5, 10, 13): Outputs for the four latches.
4. Qn (Pins 3, 6, 11, 14): Complementary outputs.
5. SET (Pins 1, 4, 9, 12): Set inputs for each latch.
6. RESET (Pins 15, 7): Reset inputs for the latches.
Each latch operates independently, and its state is controlled by the SET and RESET inputs. The Q output goes high when the SET input is high, and it is reset to low when the RESET input is high. The device operates across a wide range of supply voltages and is commonly used in digital logic applications where a memory function is required.
