1 Rev. 3 December 11 Product data sheet 1. General description The are -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. V and 5.5 V making the device suitable for translating between any of the low voltage nodes (1. V, 1.5 V, 1. V,.5 V, 3.3 V and 5. 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 7LVCHT5 holds unused or floating data inputs at a valid logic level.. Features and benefits Wide supply voltage range: V CC(A) : 1. V to 5.5 V V CC(B) : 1. V to 5.5 V High noise immunity Complies with JEDEC standards: JESD-7 (1. V to 1.95 V) JESD-5 (1. V to.7 V) JESDC (.7 V to 3. V) JESD3 (.5 V to 5.5 V) ESD protection: HBM JESD-A1F Class 3A exceeds V MM JESD-A115-B exceeds V CDM JESD-C11E exceeds 1 V Maximum data rates: Mbps (3.3 V to 5. V translation) 1 Mbps (translate to 3.3 V)) Mbps (translate to.5 V) 75 Mbps (translate to 1. V)

2 Mbps (translate to 1.5 V) Suspend mode Latch-up performance exceeds 1 ma per JESD 7B Class II ma output drive (V CC =3.V) Inputs accept voltages up to 5.5 V Low power consumption: 3 A maximum I CC I OFF circuitry provides partial Power-down mode operation Multiple package options 3.

Description bidirectional logic level-shifting application [1] State DIR CTRL OE I/O-1 I/O- Description 1 H L output input system-1 data to system- H H Z Z system- is getting ready to send data to system-1. I/O-1 and I/O- are disabled. The bus-line state depends on bus hold. 3 L H Z Z DIR bit is set LOW. I/O-1 and I/O- still are disabled. The bus-line state depends on bus hold. L L input output system- data to system-1 [1] H = HIGH voltage level; L = LOW voltage level; Z = high-impedance OFF-state Power-up considerations The device is designed such that no special power-up sequence is required other than GND being applied first.
