The IDT74FCT3807PYI is a high-performance CMOS octal non-inverting buffer/line driver designed specifically to improve system performance while using minimal power. It is ideal for driving bus lines or buffers due to an incredible output drive capability of up to ±64mA (max). With Bus Hold on all 8 channels, bus contention or data loss is prevented due to undershoot/overshoot of slow data signals.

Application Field:

The IDT74FCT3807PYI’s extraordinarily low power consumption and unusually high output drive makes it suitable for many applications in consumer, commercial, and industrial electronics. These include:

• Consumer electronics: satellite receivers, cable modems, televisions, set top boxes etc.
• Industrial controls: test and measurement, data acquisition, automation, control etc.
• Communications: optical networking, routers, switches, storage devices etc.

Working Principle:

The IDT74FCT3807PYI utilizes both NMOS and PMOS transistor pairs to achieve high-speed signal transfer in both directions. The signal is provided to the gate of the NMOS transistor, which then turns “on” and connects its drain to ground. The PMOS transistor then also turns “on” and connects its drain to the output potential of the buffer. The output capacitance of the buffer is then discharged and the signal race (situation when two signals race to ground) is prevented. This feature makes the IDT74FCT3807PYI ideal for driving the bus lines or buffers due to its increased output drive capability.

The IDT74FCT3807PYI also contains several features that make it suitable for driving bus lines. It includes active output termination, which reduces overshoot and reduces the amount of time needed to charge or discharge the output capacitance. This feature is beneficial in multi-terminal systems, where several nodes can be connected to the main bus line. In addition, the IDT74FCT3807PYI also features bus hold, which prevents bus contention and data loss.

Overall, the IDT74FCT3807PYI is a versatile, low power, high performance CMOS octal non-inverting buffer/line driver. Its high output drive capability, active output termination and bus hold features are ideal for driving bus lines or buffers and making it perfect for a variety of applications in consumer, commercial, and industrial electronics.
