SN74LS682N Information

Description

Here's a concise introduction to the SN74LS682N: The Texas Instruments SN74LS682N is an 8-bit magnitude comparator in a totem-pole or open-collector configuration. It compares two 8-bit words and provides an output indicating which word has the larger magnitude. The IC features hysteresis at its P and Q inputs, ensuring stable operations. The comparison can be made between two 8-bit words with equal length and polarity. The SN74LS682N is packaged in a dual-in-line package (PDIP) with 20 leads and has additional features such as pullup resistors on the Q input pins. This device is suitable for digital signal processing, computer interfaces, and industrial control applications where accurate comparison of data is required.

Features

The SN74LS682N is a magnitude comparator that compares two 8-bit words. Its features include:

  • Compares two 8-bit words
  • Choice of totem-pole or open-collector outputs
  • Hysteresis at P and Q inputs
  • 'LS682 has 20-k pullup resistors on the Q inputs

It's a useful component for digital circuits that require comparing binary numbers.

SN74LS682N FAQs

1.Q: Are there related parts or alternatives to the Motorola 74LS 8-bit comparator?

A: Similar parts include 74HC (CMOS) series comparators or modern equivalents like SN74LS682. Always verify pin compatibility and voltage requirements.

2.Q: What are the electrical characteristics of the 74LS comparator’s outputs?

A: Outputs provide 24mA sink current (low) and -0.4mA source current (high), with totem-pole output type for direct TTL compatibility.

3.Q: What is the package type and dimensions of the Motorola 74LS DIP20 IC?

A: It comes in a 20-pin PDIP (Plastic DIP) package: max length 26.92mm, width 6.6mm, and height 5.08mm, suitable for through-hole mounting.

4.Q: What are the recommended operating conditions for the 74LS comparator?

A: Operate at 4.85–5.25V DC, 0–70°C ambient temperature, with 45pF test load for specified propagation delay (30ns typical).

5.Q: What are the absolute maximum ratings for the 74LS DIP20 comparator?

A: Absolute max ratings include 7V supply voltage, 70°C max operating temperature, and 24mA low-level output current. Exceeding these may damage the device.

6.Q: In what applications is the Motorola 74LS 8-bit comparator typically used?

A: It’s used in digital systems for arithmetic operations, address decoding, process control, and applications requiring binary value comparison (e.g., test equipment, industrial controllers).

7.Q: What are the key features of the 74LS 8-bit comparator from Motorola?

A: Key features include 8-bit magnitude comparison, totem-pole outputs, 30ns propagation delay, 4.75–5.25V operating voltage, and LS (Low-Power Schottky) logic family compatibility.

8.Q: What is the pinout configuration of the Motorola 74LS 8-bit magnitude comparator (DIP20)?

A: The pinout follows standard 20-pin DIP layout, with inputs (A0-A7, B0-B7), outputs (A>B, A=B), power supply (VCC: pin 20, GND: pin 10), and control pins (e.g., cascading inputs). Refer to the datasheet for a detailed diagram.
