1. general description the 74hc1g125; 74hct1g125 is a high-speed, si-gate cmos device. the 74hc1g125; 74hct1g125 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 level at pin oe causes the output to assume a high-impedance off-state. the bus driver output currents are equal compared to the 74hc125 and 74hct125. 2. features n wide supply voltage range from 2.0 v to 6.0 v n symmetrical output impedance n high noise immunity n low power consumption n balanced propagation delays n esd protection: u hbm eia/jesd22-a114-c exceeds 2000 v u mm eia/jesd22-a115-a exceeds 200 v n very small 5 pins packages n speci?ed from - 40 cto+85 c and - 40 c to +125 c 3. quick reference data 74hc1g125; 74hct1g125 bus buffer/line driver; 3-state rev. 05 23 december 2005 product data sheet table 1: quick reference data gnd = 0 v; t amb =25 c; t r =t f 6.0 ns. symbol parameter conditions min typ max unit 74hc1g125 t phl , t plh propagation delay a to y v cc =5v; c l =15pf - 9 - ns c i input capacitance - 1.5 - pf c pd power dissipation capacitance v i = gnd to v cc [1] -30-pf
