Additional Details

The TC7W139F operates over a temperature range of -40°C to 85°C. The input and output pins are protected against electrostatic discharge (ESD). The device is available in a TSSOP8 package, which is suitable for surface mounting on printed circuit boards. This NAND gate can be utilized for building more complex logic functions, such as flip-flops, counters, and decoders.

The propagation delay time (tpd) represents the time it takes for the output to change state after a change in the input. The TC7W139F features a typical propagation delay of 3.6 ns at a supply voltage of 5V, which allows for high-speed data processing. The supply current (ICC) is the current drawn by the device when it is in a static state. The TC7W139F has a maximum supply current of 2 μA at a supply voltage of 5V, which minimizes power consumption. The noise immunity (VNIH and VNIL) is the ability of the device to tolerate noise on the input signals without causing a false output. The TC7W139F has a high noise immunity of 30% of the supply voltage, which ensures reliable operation in noisy environments.
