Dual-bit, dual-supply voltage level translator/transceiver;

3-state

Rev. 01 — 3 July 2007

Product data sheet

1. General description

The 74AVCH2T45 is a dual bit, dual supply transceiver that enables bidirectional level

translation. It features two data input-output ports (nA and nB), a direction control input

(DIR) 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 0.8 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 nA and DIR

are referenced to V_CC(A)and pins nB are referenced to V_CC(B). A HIGH on DIR allows

transmission from nA to nB and a LOW on DIR allows transmission from nB to nA.

The device is fully speciﬁed for partial power-down applications using I_OFF. The I_OFF

circuitry 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 A and B are in the high-impedance OFF-state.

The 74AVCH2T45 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.

2. Features

I Wide supply voltage range:

N V_CC(A): 0.8 V to 3.6 V

N V_CC(B): 0.8 V to 3.6 V

I High noise immunity

I Complies with JEDEC standards:

N JESD8-12 (0.8 V to 1.3 V)

N JESD8-11 (0.9 V to 1.65 V)

N JESD8-7 (1.2 V to 1.95 V)

N JESD8-5 (1.8 V to 2.7 V)

N JESD8-B (2.7 V to 3.6 V)

I ESD protection:

N HBM JESD22-A114E Class 3B exceeds 8000 V

N MM JESD22-A115-A exceeds 200 V

N CDM JESD22-C101C exceeds 1000 V

I Maximum data rates:

N 500 Mbps (1.8 V to 3.3 V translation)

N 320 Mbps (< 1.8 V to 3.3 V translation)

N 320 Mbps (translate to 2.5 V or 1.8 V)
