74LVCH2T45 - Dual supply translating transceiver

Download the 74LVCH2T45 datasheet PDF. This datasheet also covers the 74LVC2T45 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 74LVC2T45; 74LVCH2T45 are dual bit, dual supply translating transceivers with 3-state outputs that enable bidirectional level translation.

They feature two 2-bits input-output ports (nA and nB), 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.
  • 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-A exceeds 200 V.
  • CDM JESD22-C101E exceeds 1000 V.
  • Maximum data rate.

74LVC2T45; 74LVCH2T45 Dual supply translating transceiver; 3-state Rev. 12 — 1 March 2023 Product data sheet 1. General description The 74LVC2T45; 74LVCH2T45 are dual bit, dual supply translating transceivers with 3-state outputs that enable bidirectional level translation. They feature two 2-bits input-output ports (nA and nB), 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 nA and DIR are referenced to VCC(A) and pins nB are referenced to VCC(B). A HIGH on DIR allows transmission from nA to nB and a LOW on DIR allows transmission from nB to nA.
