74LVC126A; Quad buffer/line driver with 5 Volt tolerant input/outputs; 3-state
Philips Semiconductors Product specification
Quad buffer/line driver with 5 Volt
tolerant input/outputs; 3-state 74LVC126A
FEATURES5 V tolerant inputs/outputs for interfacing with 5 V logic Wide supply voltage range from 1.2to 3.6V CMOS low power consumption Direct interface with TTL levels Inputs accept voltages up to 5.5V Complies with JEDEC standard no. 8-1A ESD protection:
HBM EIA/JESD22-A114-A exceeds 2000V
MM EIA/JESD22-A115-A exceeds 200V. Specified from −40to +85°C and −40to +125 °C.
DESCRIPTIONThe 74LVC126A is a high-performance, low-power,
low-voltage, Si-gate CMOS device, superior to most
advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3or5 V devices. 3-state operation, outputs can handle 5V.
The 74LVC126A consistsof four non-inverting buffers/line
drivers with 3-state outputs (nY) which are controlled by
the output enable input (nOE).A LOWat nOE causes the
outputs to assume a high-impedance OFF-state.
QUICK REFERENCE DATAGND=0 V; Tamb =25 °C; tr =tf≤ 2.5 ns.

VCC= supply voltage in Volts;= total load switching outputs;
Σ(CL× VCC2×fo)= sum of the outputs. The condition is VI= GND to VCC.

RECOMMENDED OPERATING CONDITIONS
LIMITING VALUES accordance with the Absolute Maximum Rating System (IEC 60134); voltages are referencedto GND (ground=0 V).
Notes The input and output voltage ratings may be exceeded if the input and output current ratings are observed. For SO14 packages: above 70 °C the value of Ptot derates linearly with 8 mW/K.
For (T)SSOP14 packages: above 60 °C the value of Ptot derates linearly with 5.5 mW/K.
For DHVQFN14 packages: above 60 °C the value of Ptot derates linearly with 4.5 mW/K.
