Fairchild FXL Series 1-8 bit Dual Supply Translators
FXL series are Fairchild’s newest family of dual-supply translators
and are designed to translate up or down, for logic in the range of 1.0 V
to 3.3 V. Utilizing space and power conserving technologies, these are ideal
for use in ultra portables such as cell phones and digital cameras.

FXL4245, FXLH42245, FXL5T244, FXL4T245, FXL2T245
- Outputs remain in 3-state until active VCC level is reached.
Switch to 3-state if either VCC is at Gnd.
- Power-up sequencing is not required.
- Bushold and B-side series resistors - FXLH42245 (preliminary)
FXLP 34
- Smallest single bit dual VCC translator ULP technology for Ultra Low Power consumption

Fairchild LVX and VCX™ Series Dual Vcc Translators for
Up-Down / Down-Up Bi- directional translation of 1.8 V, 3.3 V., 5 Volt logic levels
 |
- Electrically isolates both sides of the device.
- VOH is driven close to supply rail, thereby reducing power consumption.
- Bidirectional and 3-state capability.
- LVXC translators have configurable capabilities: signal levels track VCC. Opposite-side inputs and VCC pin can float.
- VCX translators have high-impedance power-down capability.
|
Fairchild Open Drain Translators for Uni-directional Translation using
external Pull-up Resistors
 |
Open drain devices give the user flexibility in setting VOH with the
VCC applied to the pull-up resistor.
- Translation upward or downward determined by VCCA on
the device and VCCB on the pull-ups.
- VOH typically close to VCCB.
- No Power-up sequencing requirement.
- 3-state output capability for LCX760.
