Description
MC74LCX74DTR2G is a dual D-type, positive-edge-triggered flip-flop with asynchronous preset and clear. Each flip-flop captures D on the rising clock edge and outputs Q and Q̅. PRE and CLR are asynchronous controls that force a defined state regardless of the clock. It operates on a low-voltage CMOS supply from about 1.65 V to 3.6 V, suitable for portable/battery-powered designs. The device is designed for low power with standard CMOS input thresholds and is pin-compatible with other 74xx74 devices. Packaging suffix DTR2G indicates an 8-pin RoHS-compliant package, typically available in tape-and-reel. Common uses include small registers, counters, shift registers, data storage, and other latch-based timing logic.

Pinout
Pin count: 14 pins (14-pin package).
Function: Dual D-type positive-edge-triggered flip-flop with asynchronous clear and insert/preset (PRE) inputs; each flip-flop captures D on the rising clock edge and provides Q and Q̄ outputs (two independent flip-flops with their own PRE and CLR).
