Low-Voltage Dual Switches Deliver Analog Performance

Sept. 1, 2000

The NC7WB66K8 is claimed to be the industry's smallest leaded, dual analog CMOS bus switch with independent enables. Implemented as two separate n and p channel CMOS pairs, the pass-gate switches feature a supply voltage range of 1.65V to 5.5V. Analog performance characteristics include a typical on-resistance flatness of 8 ohms across a peak-to-peak signal range of 0V to 3V, resulting in minimal signal distortion. Additionally, on-resistance matching between the two independent switches is within 0.2 ohms. Other analog specifications include a crosstalk between channels of -70 dB at 10 MHz, and a 3-dB bandwidth of 200 MHz. The package measures 2.1 mm x 3.1 mm, including the leads, with a maximum height of 0.9 mm and a lead pitch of 0.5 mm. The device's ac specifications include a 3V propagation delay of 0.7 ns and enable/disable times of 2.5 to 3.0 ns. Pricing is $0.40 each/3,000.
