IDT74LVC241A
EXTENDED COMMERCIAL TEMPERATURE RANGE
DESCRIPTION:
The LVC241A device is designed specifically to improve both the
performance and density of 3-state memory-address drivers, clock driv-
ers, and bus-oriented receivers and transmitters. Together with the
LCV240A and LCV244A, these devices provide the choice of selected
combinations of inverting and noninverting outputs, symmetrical OE (ac-
tive-low output-enable) inputs, and complementary OE and OE inputs.
The LVC241A is organized as two 4-bit line drivers with separate output-
enable (1OE , 2OE) inputs. When 1OE is low or 2OE is high, the device
passes data from the A inputs to the Y outputs. When 1OE is high or 2OE
is low, the outputs are in the high-impedance state.
The LVC241A has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
Inputs can be driven from either 3.3V or 5V devices. This feature allows
the use of these devices as translators in a mixed 3.3V/5V system
environment.
To ensure the high-impedance state during power up or power down,
OE (OE) should be tied to VCC
(GND) through a pullup (pulldown) resistor;
the minimum value of the resistor is determined by the current-sinking
capability of the driver.
FEATURES:
– 0.5 MICRON CMOS Technology
– ESD > 2000V per MIL-STD-883, Method 3015;
> 200V using machine model (C = 200pF, R = 0)
– 1.27mm pitch SOIC, 0.65mm pitch SSOP,
0.635mm pitch QSOP, 0.65mm pitch TSSOP packages
– Extended commercial range of – 40°C to +85°C
–VCC = 3.3V ±0.3V, Normal Range
–VCC = 2.3V to 3.6V, Extended Range
– CMOS power levels (0.4W typ. static)
– Rail-to-Rail output swing for increased noise margin
– All inputs, outputs and I/O are 5 Volt tolerant
– Supports hot insertion
