74AVCH8T245
8-bit dual supply translating transceiver with configurable
voltage translation; 3-state
Rev. 02 — 28 April 2009
Product data sheet
1. General description
The 74AVCH8T245 is an 8-bit, dual supply transceiver that enables bidirectional level
translation. It features two data input-output ports (An and Bn), a direction control input
(DIR), a output enable input (OE) and dual supply pins (VCC(A) and VCC(B)). Both VCC(A)
and VCC(B) can be supplied at any voltage between 0.8 V and 3.6 V making the device
suitable for translating between any of the low voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V,
2.5 V and 3.3 V). Pins An, OE and DIR are referenced to VCC(A) and pins Bn are
referenced to VCC(B). A HIGH on DIR allows transmission from An to Bn and a LOW on
DIR allows transmission from B to A. The output enable input (OE) can be used to disable
the outputs so the buses are effectively isolated.
The device is 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 and B outputs are in the high-impedance OFF-state. The bus-hold
circuitry on the powered-up side always stays active.
The 74AVCH8T245 has active bus hold circuitry which is provided to hold unused or
floating data inputs at a valid logic level. This feature eliminates the need for external
pull-up or pull-down resistors.

[1] VCCO is the supply voltage associated with the output port.
[2] VCCI is the supply voltage associated with the data input port.
[3] The bus hold circuit can sink at least the minimum low sustaining current at VIL max. IBHL should be measured after lowering VI to GND
and then raising it to VIL max.
[4] The bus hold circuit can source at least the minimum high sustaining current at VIH min. IBHH should be measured after raising VI to VCC
and then lowering it to VIH min.
[5] An external driver must source at least IBHLO to switch this node from LOW to HIGH.
[6] An external driver must sink at least IBHHO to switch this node from HIGH to LOW.
[7] For I/O ports, the parameter IOZ includes the input leakage current.

[1] 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.

specified use without further testing or modification.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) may cause permanent
damage to the device. Limiting values are stress ratings only and operation of
the device at these or any other conditions above those given in the
Characteristics sections of this document is not implied. Exposure to limiting
values for extended periods may affect device reliability.
Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is intended
for quick reference only and should not be relied upon to contain detailed and
full information. For detailed and full information see the relevant full data
sheet, which is available on request via the local NXP Semiconductors sales
office. In case of any inconsistency or conflict with the short data sheet, the
full data sheet shall prevail.
Terms and conditions of sale — NXP Semiconductors products are sold
subject to the general terms and conditions of commercial sale, as published
at http://www.nxp.com/profile/terms, including those pertaining to warranty,
intellectual property rights infringement and limitation of liability, unless
explicitly otherwise agreed to in writing by NXP Semiconductors. In case of
