INTEGRATED CIRCUITS 74LVC125 Quad buffer/line driver; 3-State Product specification Supersedes data of February 1996 IC24 Data Handbook 1997 Mar 18 Philips Semiconductors Product specification Quad buffer/line driver; 3-State 74LVC125 FEATURES DESCRIPTION • Wide supply voltage range of 1.2 to 3.6 V • In accordance with JEDEC standard no. 8-1A • Inputs accept voltages up to 5.5 V • CMOS lower power consumption • Direct interface with TTL levels • Output drive capability 50 transmission lines at 85°C The 74LVC125 is a high performance, low-power, low-voltage Si-gate CMOS device and superior to most advanced CMOS compatible TTL families. The 74LVC125 consists of four non-inverting buffers/line drivers with 3-State outputs. The 3-State outputs (nY) are controlled by the output enable input (nOE). A HIGH at nOE causes the outputs to assume a high impedance OFF-state.
