 Features
 Wide supply voltage range:
− 1.08 V to 3.6 V on A port
− 1.65 V to 5.5 V on B port (VCCA ≤ VCCB)
 Maximum data rates: 110 Mbps (Push pull)
 Low supply current: ICCA + ICCB = 1 μA
 VCC isolation feature: If either VCCA or VCCB
input is at GND, all outputs are in the
high-impedance state
 OE input circuit referenced to VCCA
 No power-supply sequencing required. VCCA or
VCCB can be ramped first
 IOFF supports partial power-down mode
operation
 ESD protection exceeds
− ±8000 V Human-body model(JS001)
− ±2000 V Charged-device model(JS002)
 Operating temperature range: -40°C to 85°C
 Applications

 Description
The DIO7B104 is a 4-bit bidirectional voltage level
translator with output enable (OE) pin. The device
uses two separate configurable power-supply rails.
The A port is designed to track VCCA and the VCCA
supplies voltage from 1.08 V to 3.6 V, so DIO7B104
meets the requirement of low voltage system
application. The B port is designed to track VCCB and
VCCB supply voltage from 1.65 V to 5.5 V. VCCA
should not exceed VCCB. This allows for universal
low-voltage bidirectional translation between any of
the 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V voltage
system.
The DIO7B104 has an output enable pin which
control the output status. When the OE input is low,
all I/Os are placed in the high-impedance state. Pins
of A port and OE are referenced to VCCA and pins of B
port are referenced to VCCB.
This device is fully specified for partial power-down
applications using IOFF. The IOFF circuitry disables the
output, preventing the damaging backflow current
through the device when it is powered down.
The DIO7B104 is available in TSSOP-14 and
QFN2.0*1.7-12 packages. It is specified over ambient
temperature range of -40°C to 85°C, which meets the
requirements of industry and consumer applications.
