74LVC1T45 - Dual supply translating transceiver

General Description

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

They feature two 1-bit input-output ports (A and B), a direction control input (DIR) and dual supply pins (VCC(A) and VCC(B)).

Key Features

  • Wide supply voltage range:.
  • VCC(A): 1.2 V to 5.5 V.
  • VCC(B): 1.2 V to 5.5 V.
  • High noise immunity.
  • 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).
  • 60 Mbps (translate to 1.5 V).
  • Suspend mode.
  • Latch-up performance exceeds 100 mA per JESD 78 Class II.
  • ±24 mA output drive (VCC = 3.0.

74LVC1T45; 74LVCH1T45 Dual supply translating transceiver; 3-state Rev. 9 — 10 February 2022 Product data sheet 1. General description The 74LVC1T45; 74LVCH1T45 are single bit, dual supply transceivers with 3-state outputs that enable bidirectional level translation. They feature two 1-bit input-output ports (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.
