The CD4007UBE is a specialty function logic dual complementary pair plus device manufactured by Texas Instruments. This device is a high-speed CMOS TTL integrated circuit that can be used for various purposes. The CD4007UBE consists of two high-speed complementary gates (INV GATE and NOT GATE), four 2-input AND and four OR gates. It features a special input pre-design function select input, which can be used to select a logic 1 or logic 0 by applying a voltage between logic 0 and logic 1 levels. In addition, the device can operate at high speeds and low power consumption. It has an operating voltage of 4.5V to 5.5V and a minimum noise margin of 0.8V. The CD4007UBE is ideal for applications such as logic buffers, data selectors, multiplexers, and decoders.
