74AHC2G126; 74AHCT2G126
Dual buffer/line driver; 3-state
Rev. 02 -- 21 September 2004 Product data sheet
1. General description
The 74AHC2G126; AHCT2G126 is a high-speed Si-gate CMOS device. The 74AHC2G126; AHCT2G126 provides a dual non-inverting buffer/line driver with 3-state output. The 3-state output is controlled by the output enable input (OE). A LOW at pin nOE causes the output to assume a high-impedance OFF-state.
2. Features
s Symmetrical output impedance s High noise immunity s ESD protection: x HBM EIA/JESD22-A114-B exceeds 2000 V x MM EIA/JESD22-A115-A exceeds 200 V x CDM EIA/JESD22-C101 exceeds 1000 V. s Low power dissipation s Balanced propagation delays s Multiple package options s Specified from -40 C to +85 C and from -40 C to +125 C.

CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD x VCC2 x fi x N + (CL x VCC2 x fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = total load switching outputs; (CL x VCC2 x fo) = sum of the outputs. The condition is VI = GND to VCC.

[1] [2] Typical values are measured at VCC = 5.0 V. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD x VCC2 x fi x N + (CL x VCC2 x fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = total load switching outputs; (CL x VCC2 x fo) = sum of the outputs. The condition is VI = GND to VCC.
