8-bit dual supply translating transceiver; 3-state

Rev. 1 — 11 February 2020

Product data sheet

1. General description

The 74AXP8T245 is an 8-bit dual supply translating transceiver with 3-state outputs that enable

bidirectional level translation. It features two data input-output ports (pins An and Bn), a direction

control input (DIR), an output enable input (OE) and dual supply pins (V_CC(A)and V_CC(B)). Both

V_CC(A)and V_CC(B)can be supplied at any voltage between 0.9 V and 5.5 V making the device

suitable for translating between any of the low voltage nodes (0.9 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V,

3.3 V and 5.0 V). No power supply sequencing is required and output glitches during power supply

transitions are prevented using patented circuitry. As a result glitches will not appear on the outputs

for supply transitions during power-up/down between 20 mV/µs and 5.5 V/s.

Pins An, OE and DIR are referenced to V_CC(A)and pins Bn are referenced to V_CC(B). A HIGH on

DIR allows transmission from An to Bn and a LOW on DIR allows transmission from Bn to An. The

output enable input (OE) can be used to disable the outputs so the buses are effectively isolated.

The devices are fully specified for partial power-down applications using I_OFF. The I_OFFcircuitry

disables the output, preventing any damaging backflow current through the device when it is

powered down. In suspend mode when either V_CC(A)or V_CC(B)are at GND level, both An and Bn

are in the high-impedance OFF-state.

2. Features and benefits

•

Wide supply voltage range:

•

V_CC(A): 0.9 V to 5.5 V

V_CC(B): 0.9 V to 5.5 V

•

Low output capacitance; C_O= 3.8 pF (typical)

Low dynamic power consumption; C_PD= 10 pF (typical)

Low static power consumption; I_CC= 2 μA (25 °C maximum)

High noise immunity

Complies with JEDEC standard:

•

JESD8-12 (1.1 V to 1.3 V; inputs)

JESD8-11 (1.4 V to 1.6 V)

JESD8-7 (1.65 V to 1.95 V)

JESD8-5 (2.3 V to 2.7 V)

JESD8C (2.7 V to 3.6 V)

JESD12-6 (4.5 V to 5.5 V)

•

ESD protection:

•

HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2 kV

CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1 kV

•

Latch-up performance exceeds 100 mA per JESD78D Class II

Inputs accept voltages up to 5.5 V

Low noise overshoot and undershoot < 10% of V_CCO

I_OFFcircuitry provides partial power-down mode operation

Definitions

Limiting values — Stress above one or more limiting values (as defined in

the Absolute Maximum Ratings System of IEC 60134) will cause permanent

damage to the device. Limiting values are stress ratings only and (proper)

operation of the device at these or any other conditions above those

given in the Recommended operating conditions section (if present) or the

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.
