INTEGRATED CIRCUITS DATA SHEET 74HC2G125; 74HCT2G125 Dual buffer/line driver; 3-state Product specication Supersedes data of 2003 Jan 31 2003 Mar 03 Philips Semiconductors Product specication Dual buffer/line driver; 3-state FEATURES Wide supply voltage range from 2.0 to 6.0 V Symmetrical output impedance High noise immunity Low power dissipation Balanced propagation delays Very small 8 pins package Output capability: bus driver ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V. Specified from 40 to +85 °C and 40 to +125 °C. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf ≤ 6.0 ns. 74HC2G125; 74HCT2G125 DESCRIPTION The 74HC2G/HCT2G125 is a high-speed Si-gate CMOS device. The 74HC2G/HCT2G125 provides one non-inverting buffer/line driver with 3-state output. The 3-state output is controlled by the output enable input pin (OE). A HIGH at pin OE causes the output to assume a high-impedance OFF-state. The bus driver output currents are equal compared to the 74HC/HCT125.
