概述

Description

MC74LCX74DTR2G is a dual D-type, positive-edge-triggered flip-flop from the LCX CMOS family. Key points:
- Two independent flip-flops inside one 8-pin package.
- Each FF samples D on the rising edge of the clock input (CP) and outputs Q (and its complement Q̅).
- Includes asynchronous clear (CLR) and preset (PRE) inputs, both active-low, to force Q or Q̅ regardless of clock.
- Low-voltage CMOS device (typical LCX operating range; see datasheet for exact Vcc range).
- Packaging: DTR2G — tape-and-reel, RoHS-compliant, 8-pin small-outline.
Common uses: data storage and transfer, edge-triggered synchronization, state machines, and simple frequency division.
Truth outline: when PRE or CLR is asserted (low), Q outputs are forced accordingly; when both are deasserted, Q follows the D input on each rising clock edge. Suitable for 3.3V or other low-voltage logic interfaces (verify supply range in the datasheet).

Features

MC74LCX74DTR2G features (concise):
- Dual D-type positive-edge-triggered flip-flops
- Independent D, CLK, PRE (set), and CLR (reset) inputs for each flip-flop
- Asynchronous PRE and CLR (active low)
- Q and Q̄ outputs for each flip-flop
- Low-power CMOS LCX technology
- Typical industrial temperature range (-40°C to 85°C)
- Packaging: DTR (tape & reel), RoHS-compliant (lead-free)

Package

It’s a 14-pin Small Outline IC (SOIC) in a D‑package; the DTR2G suffix denotes tape‑and‑reel RoHS packaging.

Pinout

- Pin count: 14 pins (14-pin package, e.g., SOIC-14/TSSOP-14 for MC74LCX74DTR2G)
- Function: Dual positive-edge-triggered D-type flip-flops with asynchronous preset (PRE) and clear (CLR) inputs. Each flip-flop has D, CLK, PRE, CLR inputs and Q, Q̅ outputs; captures D on the rising clock edge.

Manufacturer

- Manufacturer: ON Semiconductor (the brand from Motorola’s former semiconductor division).
- What kind of company: An American multinational semiconductor manufacturer that designs and manufactures ICs and discrete components for automotive, industrial, and consumer electronics.

Application

MC74LCX74DTR2G is a dual D-type flip-flop with asynchronous preset and clear. Applications:
- Data storage and transfer in synchronous systems (registers, pipelines, shift registers)
- Timing and sequencing circuits (clocked delays, state machines)
- Clock-domain crossing and data synchronization between clocks
- Power-up/reset control using preset/clear for defined startup states
- Simple counters/dividers and small memory elements in low-power designs
