Microchip Technology TC4469EJD Quad CMOS Buffer/Driver
The TC4469EJD from Microchip Technology is a versatile quad CMOS buffer/driver designed to provide a high-current drive capability with minimal cross-conduction. This device is part of the TC4469 family and is engineered to convert TTL or CMOS input levels into CMOS output levels, making it ideal for interfacing and driving power loads.
Each driver in the TC4469EJD is capable of driving a 1000pF capacitive load with a 25ns propagation delay and 20ns transition time. This makes it an excellent choice for driving highly capacitive loads such as MOSFET gates, as well as other high-current applications. The device operates over a wide voltage range of 4.5V to 18V, providing flexibility for various applications and ensuring compatibility with most logic families.
The TC4469EJD is housed in a robust 14-pin SOIC package, ensuring a compact footprint while maintaining operational integrity. Its high peak output current, up to 1.5A per channel, allows it to drive large capacitive loads with ease, while the matched rise and fall times reduce the risk of output signal distortion.
With its low supply current, the device is not only powerful but also energy-efficient. It features latch-up protection for all inputs and outputs, providing additional safety and reliability for the user's application. The TC4469EJD is also characterized for operation from -40°C to 85°C, making it suitable for a wide range of industrial and automotive environments.
Applications for the TC4469EJD include driving power MOSFETs, piezoelectric transducers, LED displays, and relays. It can also be used in motor control circuits, power supply circuits, and as a line driver for data communications. With its high-drive capability and robust design, the TC4469EJD from Microchip Technology is an excellent choice for designers looking for a reliable and efficient solution to handle high-power driving tasks.
