Philips Semiconductors
Product specification
Bus buffer/line driver; 3-state
74HC1G126; 74HCT1G126
FEATURES
Wide operating voltage from 2.0 to 6.0 V
Symmetrical output impedance
High noise immunity
Low power dissipation
Balanced propagation delays
Very small 5 pins package
Output capability: bus driver.
DESCRIPTION
The 74HC1G/HCT1G126 is a highspeed Si-gate CMOS
device.
The 74HC1G/HCT1G126 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 LOW at
pin OE causes the output as assume a high-impedance
OFF-state.
The bus driver output currents are equal compared to the
74HC/HCT126.
