Voltage Level Translator 6-Pin SC-70 T/R

This one-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.65 V to 3.6 V. The B port is designed to track VCCB. VCCA must be less than or equal to VCCB. VCCB accepts any supply voltage from 2.3 V to 5.5 V. This allows for low-voltage bidirectional translation between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

No Direction-Control Signal Needed

Maximum Data Rates

• 24 Mbps (Push Pull)
• 2 Mbps (Open Drain)

Available in the Texas Instruments NanoFree™ Package

1.65 V to 3.6 V on A port and 2.3 V to 5.5 V on
B port (V_CCA =V_CCB)

V_CC Isolation Feature – If Either V_CC Input Is at GND,
Both Ports Are in the High-Impedance State

No Power-Supply Sequencing Required – Either V_CCA or
V_CCB Can be Ramped First

I_off Supports Partial-Power-Down Mode Operation

Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II

ESD Protection Exceeds JESD 22
