74LVC1T45
Single-Bit Dual-Supply Bus Transceiver
with Configurable Voltage Translation
GENERAL DESCRIPTION
FEATURES
The 74LVC1T45 is a single-bit, dual-supply bus
transceiver with configurable voltage translation. The
device has two separate configurable power-supply
rails. The A and B ports track the VCCA supply and VCCB
supply respectively. The supply voltage pins accept
voltage range from 1.65V to 5.5V, which makes the
device suitable for low voltage bidirectional translation
voltage nodes of 1.8V, 2.5V, 3.3V, and 5V.
● VCCA Supply Voltage Range: 1.65V to 5.5V
● VCCB Supply Voltage Range: 1.65V to 5.5V
● DIR Input Circuit Referenced to VCCA
● +32mA/-32mA Output Current
● Data Rates
420Mbps (3.3V to 5V Translation)
210Mbps (Translate to 3.3V)
140Mbps (Translate to 2.5V)
75Mbps (Translate to 1.8V)
The 74LVC1T45 features that two data buses can
communicate asynchronously. Either the A port outputs
or the B port outputs can be activated by DIR logic
levels. The DIR input circuit is supplied by VCCA. When
B port outputs are activated, the device allows the data
to transmit from A bus to B bus. On the contrary, when
A port outputs are activated, the device allows the data
to transmit from B bus to A bus. The input circuit is
always active on the two ports. A logic level of high or
low must be set to avoid excessive supply current.
● Outputs in High-Impedance State when VCCA or
V
CCB = 0V
● -40℃ to +125℃ Operating Temperature Range
● Available in Green SC70-6, SOT-23-6 Packages

ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performancedegradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
