74LVCH1T45 - Dual supply translating transceiver

Download the 74LVCH1T45 datasheet PDF. This datasheet also covers the 74LVC1T45 variant, as both devices belong to the same dual supply translating transceiver family and are provided as variant models within a single manufacturer datasheet.

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.
