74LVC1T45 - Dual Supply Translating Transceiver

Description

The 74LVC1T45; 74LVCH1T45 are single bit, dual supply transceivers with 3-state outputs that enables bidirectional level translation.

They feature one data input-output port (A and B), a direction control input (DIR) and dual supply pins (VCC(A) and VCC(B)).

Features

  • I Wide supply voltage range: N VCC(A): 1.2 V to 5.5 V N VCC(B): 1.2 V to 5.5 V I High noise immunity I Complies with JEDEC standards: N JESD8-7 (1.2 V to 1.95 V) N JESD8-5 (1.8 V to 2.7 V) N JESD8C (2.7 V to 3.6 V) N JESD36 (4.5 V to 5.5 V) I ESD protection: N HBM JESD22-A114E Class 3A exceeds 4000 V N CDM JESD22-C101C exceeds 1000 V I Maximum data rates: N 420 Mbps (3.3 V to 5.0 V translation) N 210 Mbps (translate to 3.3 V)) N 140 Mbps (translate to 2.5 V) N 75 Mbps (translate to 1.8 V) N 60 M.

General description The 74LVC1T45; 74LVCH1T45 are single bit, dual supply transceivers with 3-state outputs that enables bidirectional level translation. They feature one data input-output port (A and B), a direction control input (DIR) and dual supply pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(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 A and DIR are referenced to VCC(A) and pin B is referenced to VCC(B). A HIGH on DIR allows transmission from A to B and a LOW on DIR allows transmission from B to A.
