74LVC8T245; 74LVCH8T245

8-bit dual supply translating transceiver; 3-state

Rev. 3 — 12 December 2011

Product data sheet

1. General description

The 74LVC8T245; 74LVCH8T245 are 8-bit dual supply translating transceivers with

3-state outputs that enable bidirectional level translation. They feature 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 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 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_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 port and B port are in the high-impedance OFF-state.

Active bus hold circuitry in the 74LVCH8T245 holds unused or floating data inputs at a

valid logic level.

2. Features and benefits

 Wide supply voltage range:

 V_CC(A): 1.2 V to 5.5 V

 V_CC(B): 1.2 V to 5.5 V

 High noise immunity

 Complies with JEDEC standards:

 JESD8-7 (1.2 V to 1.95 V)

 JESD8-5 (1.8 V to 2.7 V)

 JESD8C (2.7 V to 3.6 V)

 JESD36 (4.5 V to 5.5 V)

 ESD protection:

 HBM JESD22-A114F Class 3A exceeds 4000 V

 MM JESD22-A115-B exceeds 200 V

 CDM JESD22-C101E exceeds 1000 V

 Maximum data rates:

 420 Mbps (3.3 V to 5.0 V translation)

 210 Mbps (translate to 3.3 V))

 140 Mbps (translate to 2.5 V)

 75 Mbps (translate to 1.8 V)
