74AVCH1T45
SINGLE BIT DUAL POWER SUPPLY TRANSLATING
TRANSCEIVER WITH 3 STATE OUTPUTS
Description
The 74AVCH1T45 is a single bit, dual supply transceiver with 3-state
outputs suitable for transmitting a single logic bit across different
voltage domains. The 74AVCH1T45 is a variant of the 74AVC1T45
that includes a bus hold feature at each input. The A input/output pin
is designed to track V
CCA
while the B input/output tracks V
CCB
. This
arrangement allows for universal low-voltage translation between any
voltages from 1.2V to 3.6V. The Direction pin (DIR) controls the
direction of the transceiver and in a logic voltage related to V
CCA
.
When a high logic level is applied to DIR the A pin becomes an input
and the B pin becomes the output. Conversely the roles of A and B
are reversed when DIR is asserted low.
The 3-state feature occurs when either of the power supply voltages
are zero. This is also an Ioff feature and allows for the output to
remain in a high impedance state with both power supplies at 0V
preventing damaging backflow currents and providing power down
electrical isolation up to 3.6 V as not to interfere with any logic activity
on pin A or B.
The bus hold feature maintains the previous logic level therefore a
valid logic level is always present eliminating the need for additional
resistors for an unused or disconnected inputs.
