FXLH42245 Datasheet | Fairchild Semiconductor

Description The FXLH42245 is a configurable dual-voltage-supply translator designed for bi-directional voltage translation of signals between two voltage levels. The device allows translation between voltages as high as 3.6V to as low as 1.1V. The A Port tracks the VCCA level, and the B Port tracks the VCCB level. Both ports are designed to accept supply voltage levels from 1.1V to 3.6V. This allows for bidirectional voltage translation over a variety of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device remains in 3-STATE until both VCCs reach active levels allowing either VCC to be powered-up first. The device also contains power down control circuits that place the device in 3-STATE if either VCC is removed. The Transmit/Receive (T/R) input determines the direction of data flow through the device. The OE input, when HIGH, disables both the A and B Ports by placing them in a 3-STATE condition. The FXLH42245 is designed so that the control pins (T/R and OE) are supplied by VCCA. Features s Bi-directional interface between any 2 levels from 1.1V to 3.6V s Fully configurable, inputs track VCC level s Non-preferential power-up sequencing; either VCC may be powered-up first s Outputs remain in 3-STATE until active VCC level is reached s Outputs switch to 3-STATE if either VCC is at GND s Bushold on data inputs eliminates the need for external pull-up/pull-down resistors s 26Ω output series resistors on the B Port to reduce line noise s Power-off protection s Control inputs (T/R, OE) levels are referenced to VCCA voltage s Packaged in 24-terminal MLP s ESD protection exceeds: - 4k V HBM ESD (per JESD22-A114 & Mil Std 883e 3015.7) - 8k V HBM I/O to GND ESD (per JESD22-A114 & Mil Std 883e 3015.7) - 1k V CDM ESD (per ESD STM 5.3) - 200V MM ESD (per JESD22-A115 & ESD STM5.2) Ordering Code: Order Number FXLH42245MPX Package Number MLP024B Package Description 24-Terminal Molded Leadless Package (MLP), JEDEC MO-220, 3.5mm x 4.5mm © 2004 Fairchild Semiconductor...
