74LVC1T45; 74LVCH1T45
Dual supply translating transceiver; 3-state
Rev. 02 — 19 January 2010
Product data sheet
1. General description
The 74LVC1T45; 74LVCH1T45 are single bit, dual supply transceivers with 3-state outputs
that enables bidirectional level translation. They feature one data input-output port (A and
B), a direction control input (DIR) and dual supply pins (VCC(A) and VCC(B)). Both VCC(A)
and VCC(B) can be supplied at any voltage between 1.2 V and 5.5 V making the 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 VCC(A) and pin B is referenced to
VCC(B). A HIGH on DIR allows transmission from A to B and a LOW on DIR allows
transmission from B to A.
The devices are fully specified for partial power-down applications using IOFF. The IOFF
circuitry disables the output, preventing any damaging backflow current through the
device when it is powered down. In suspend mode when either VCC(A) or VCC(B) are at
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.

CPD is used to determine the dynamic power dissipation (PD in μW).
PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
Σ(CL × VCC2 × fo) = sum of the outputs.
[2]
fi = 10 MHz; VI = GND to VCC; tr = tf = 1 ns; CL = 0 pF; RL = ∞ Ω.

14.2 Bidirectional logic level-shifting application
Figure 16 shows the 74LVC1T45; 74LVCH1T45 being used in a bidirectional logic
level-shifting application. Since the device does not have an output enable pin, the system
designer should take precautions to avoid bus contention between system-1 and
system-2 when changing directions.

14.3 Power-up considerations
The device is designed such that no special power-up sequence is required other than
GND being applied first.

14.4 Enable times
Calculate the enable times for the 74LVC1T45; 74LVCH1T45 using the following formulas:
•
•
•
•
tPZH (DIR to A) = tPLZ (DIR to B) + tPLH (B to A)
tPZL (DIR to A) = tPHZ (DIR to B) + tPHL (B to A)
tPZH (DIR to B) = tPLZ (DIR to A) + tPLH (A to B)
tPZL (DIR to B) = tPHZ (DIR to A) + tPHL (A to B)
In a bidirectional application, these enable times provide the maximum delay from the
time the DIR bit is switched until an output is expected. For example, if the 74LVC1T45;
74LVCH1T45 initially is transmitting from A to B, then the DIR bit is switched, the B port of
the device must be disabled before presenting it with an input. After the B port has been
disabled, an input signal applied to it appears on the corresponding A port after the
specified propagation delay.
