Bus buffer/line driver; 3-state
1. General description
The 74LVC1G126 provides one non-inverting buffer/line driver with 3-state output. The
3-state output is controlled by the output enable input (OE). A LOW-level at pin OE
causes the output to assume a high-impedance OFF-state.
The input can be driven from either 3.3 Vor5 V devices. This feature allows the use of
this device in a mixed 3.3V and5 V environment.
This device is fully specified for partial power-down applications using IOFF. The IOFF
circuitry disables the output, preventing the damaging backflow current through the device
when it is powered down.
2. Features and benefits Wide supply voltage range from 1.65Vto 5.5V High noise immunity Complies with JEDEC standard: JESD8-7 (1.65 V to 1.95 V) JESD8-5 (2.3 V to 2.7 V) JESD8B/JESD36 (2.7 V to 3.6 V) 24 mA output drive (VCC =3.0V) ESD protection: HBM JESD22-A114F exceeds 2000V MM JESD22-A115-A exceeds 200 V CMOS low power consumption Inputs accept voltages up to 5V Latch-up performance exceeds 250 mA Direct interface with TTL levels Multiple package options Specified from 40 Cto+85 C and 40 Cto +125 C
