TinyLogic Portfolio Gains Four Dual 3-State Buffers

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 V_cc operating range, the inputs and outputs are high impedance when V_cc is 0V. Inputs tolerate voltages up to 5.5V independent of Vcc operating range, while outputs tolerate voltages above V_cc 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.
