概述
Description
Key features include:
1. Octal Latch Design: Features eight latches, providing eight parallel data storage locations.
2. 3-State Outputs: Allows for direct bus interfacing, with the ability to tri-state the output to prevent data collision on the bus.
3. High-Speed Performance: Operates at higher speeds compared to standard CMOS devices, making it suitable for high-frequency applications.
4. Wide Voltage Range: Functions effectively over a broad range of supply voltages, enhancing compatibility with various systems.
5. Low Power Consumption: Benefits from CMOS technology, ensuring energy efficiency.
The SNJ54HC373FK is ideal for applications that require reliable data storage and retrieval in digital circuits.
Equivalent
1. 74HC373
2. CD74HCT373
3. SN74HC373N
4. MC74HC373
These parts generally have similar functionality, operating voltage, and logic family, but always check the datasheets for exact specifications and compatibility.
Features
1. High-Speed CMOS Technology: Offers fast switching speeds with low power consumption compared to traditional TTL logic devices.
2. Wide Supply Voltage Range: Operates between 2V to 6V, providing flexibility for various applications.
3. 3-State Outputs: Allows multiple devices to share a common output line without interference, which is essential for bus-oriented systems.
4. Latch Enable Control: The device features a latch enable pin that controls data storage. When high, data is latched; when low, data is transparent.
5. Input/Output Characteristics: Inputs are TTL-compatible, and outputs are capable of driving 10 LSTTL loads.
6. Military-Grade Reliability: As part of the SNJ series, it's designed to meet strict military standards for reliability and performance under extreme conditions.
7. Package Format: Available in ceramic flat-pack for durability and thermal resistance, making it suitable for demanding environments.
These features make the SNJ54HC373FK suitable for a wide range of digital applications, including buffering, memory address latching, and data bus interfacing.
Pinout
1. D0-D7 (Pins 3-6, 11-14): These are data input pins for the octal latch.
2. Q0-Q7 (Pins 2, 5, 6, 9-12, 15): These are the 3-state output pins for the latched data.
3. LE (Pin 11): Latch Enable input, active high; controls the latching of data.
4. OE (Pin 1): Output Enable input, active low; controls whether the outputs are in a high-impedance state or reflect the latched data.
5. VCC (Pin 20): Supply voltage pin.
6. GND (Pin 10): Ground pin.
The device functions as a latch where data present at the inputs can be retained at the outputs when the latch enable is high. The outputs can be disabled regardless of the latch state using the Output Enable pin, placing them in a high-impedance state.
