TinyLogic Portfolio Gains Four Dual 3-State Buffers

Feb. 1, 2001

The addition of four new CMOS 3-state dual buffers in the US8 package has particular value to OEMs making portable battery-powered products, such as cell phones and mobile computers. The new NC7WZ125K8 and NC7WZ126K8 functions are dual non-inverting buffers with an active high and an active low to enable the high impedance state. The NC7WZ240K8 is a dual inverting buffer with active low enable for the high Z state, while the NC7WZ241K8 dual buffers version combines independent 125 and 126 functions within the same package. Specified to operate over the 1.65V to 5.5V Vcc operating range, the inputs and outputs are high impedance when Vcc is 0V. Inputs tolerate voltages up to 5.5V independent of Vcc operating range, while outputs tolerate voltages above Vcc when in the 3-state condition. The US8 package measures just 2.0 mm x 3.1 mm, including the leads, with a maximum height of 0.7 mm, easily qualifying the devices for use in compact low-profile products, such as laptops, cell phones, digital cameras, PDAs and PCMCIA cards. The new logic functions are priced at $0.34 each/10,000.
