This IC features two independent D-type flip-flops equipped with set and reset inputs, all contained within a single package. It is designed for general-purpose digital logic applications, offering low power consumption and high noise immunity, which makes it suitable for a wide range of industrial and consumer electronics.

Pinout Configuration

The MC14013BDTR2G is available in a TSSOP-14 surface-mount package. The pinout is logically arranged for ease of circuit design.

Flip-Flop 1: Pins 1 (Q1), 2 (\\(\overline{Q1}\\)), 3 (Clock 1), 4 (Reset 1), 5 (Data 1), 6 (Set 1).

Flip-Flop 2: Pins 8 (Set 2), 9 (Data 2), 10 (Reset 2), 11 (Clock 2), 12 (\\(\overline{Q2}\\)), 13 (Q2).

Power Supply: Pin 14 (VDD) is the positive supply rail, and Pin 7 (VSS) is ground.

Key Datasheet Specifications

Critical parameters from the datasheet define the IC's operational limits and performance:

Supply Voltage Range (VDD): -0.5V to +18V (absolute maximum), with a typical operating range of 3V to 16V.

Low Power Consumption: Very low static power dissipation, typically in the nanowatt range, making it ideal for battery-operated devices.

High Noise Immunity: 0.45 VDD (typ.) provides excellent resistance to electrical noise in the environment.

Operating Temperature Range: -55°C to +125°C, ensuring performance stability in harsh environments.

Output Drive Capability: Can drive two low-power TTL loads or one low-power Schottky TTL load over the entire temperature range.

Application Circuit Example: A Frequency Divider

One of the most common uses of a D-type flip-flop is to create a divide-by-two counter. This circuit is fundamental in clock division and frequency scaling applications.

1. Circuit Setup: Use one of the two flip-flops inside the MC14013BDTR2G. Connect the Data input (D) directly to the complementary output (\\(\overline{Q}\\)).

2. Operation: The incoming clock signal is applied to the Clock (CLK) input. On each rising edge of the clock pulse, the flip-flop toggles its state. The output signal at Q is exactly half the frequency of the input clock signal.

3. Cascading: By connecting the output (Q) of the first flip-flop to the clock input of the second, a divide-by-four circuit is created. This demonstrates how multiple flip-flops can be cascaded for higher division ratios, forming the basis of binary counters.

This simple yet effective circuit highlights the component's utility in digital counters, registers, and memory elements.

ICGOODFIND Summary

The Onsemi MC14013BDTR2G is a versatile and robust dual D-type flip-flop that serves as a fundamental building block in digital design. Its wide operating voltage, low power consumption, and high noise immunity make it a preferred choice for designers creating timing, control, and sequential logic circuits. Whether used in a simple switch debouncer or a complex counter chain, this IC provides dependable performance.
