74LVC1T45; 74LVCH1T45
Dual supply translating transceiver; 3-state
Rev. 6 6 August 2012 Product data sheet
1. General description
The 74LVC1T45; 74LVCH1T45 are single bit, dual supply transceivers with 3-state
outputs that enable bidirectional level translation. They feature two 1-bit input-output ports
(A and B), a direction control input (DIR) and dual supply pins (V and V ). Both
CC(A) CC(B)
V and V can be supplied at any voltage between 1.2 V and 5.5 V making the
CC(A) CC(B)
device suitable for translating between any of the low voltage nodes (1.2 V, 1.5 V, 1.8 V,
2.5 V, 3.3 V and 5.0 V). Pins A and DIR are referenced to V and pin B is referenced
CC(A)
to V . A HIGH on DIR allows transmission from A to B and a LOW on DIR allows
CC(B)
transmission from B to A.
The devices are fully specified for partial power-down applications using I . The I
OFF OFF
circuitry disables the output, preventing any damaging backflow current through the
device when it is powered down. In suspend mode when either V or V are at
CC(A) CC(B)
GND level, both A port and B port are in the high-impedance OFF-state.
Active bus hold circuitry in the 74LVCH1T45 holds unused or floating data inputs at a valid
logic level.
