Voltage Level Translator Bidirectional 1 Circuit 8 Channel 60Mbps 20-TSSOP This device is an 8-bit non-inverting level translator which uses two separate configurable power-supply rails. The A port tracks the VCCA pin supply voltage. The VCCA pin accepts any supply voltage between 1.4V and 3.6V. The B port tracks the VCCB pin supply voltage. The VCCB pin accepts any supply voltage between 1.65V and 5.5V. Two input supply pins allows for low Voltage bidirectional translation between any of the 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes. When the output-enable (OE) input is low, all outputs are placed in the high-impedance (Hi-Z) state. To put the device in the Hi-Z state during power-up or power-down periods, tie OE to GND through a pulldown resistor. The current-sourcing capability of the driver determines the minimum value of the resistor. • No direction-control signal needed • Maximum data rates: – 110Mbps (push pull) – 1.2Mbps (open drain) • 1.4V to 3.6V on A port and 1.65V to 5.5V on B port (VCCA ≤ VCCB) • No power-supply sequencing required – either VCCA or VCCB can be ramped first • Latch-up performance exceeds 100mA per JESD 78, class II • ESD protection exceeds JESD 22 (A port): – 2000 V Human Body Model (A114-B) – 150 V Machine Model (A115-A) – 1000 V Charged-Device Model (C101) • IEC 61000-4-2 ESD (B-port): – ± 8kV Contact Discharge – ± 6kV Air Discharge #commonpartslibrary #integratedcircuit #logic #translator #levelshifter
