General description

The 74LVC2952A is a high-performance, low power, low voltage, Si-gate CMOS device superior to most advanced CMOS compatible TTL families.

Inputs can be driven from either 3.3 V or 5 V devices. In 3-state operation, outputs can handle 5 V. These features allow the use of these devices as translators in a mixed 3.3 V and 5 V environment.

The 74LVC2952A is an octal non-inverting registered transceiver. Two 8-bit back-to-back registers store data flowing in both directions between two bidirectional buses. Data applied to the inputs is entered and stored on the rising edge of the clock (CPAB, CPBA) provided that the clock enable (CEAB, CEBA) input is LOW. The data is then present at the 3-state output buffers, but is only accessible when the output enable (OEAB, OEBA) input is LOW. Data flow from A inputs to B outputs is the same as for B inputs to A outputs.

Features

  • 5 V tolerant inputs/outputs for interfacing with 5 V logic
  • Supply voltage range from 1.2 V to 3.6 V
  • CMOS low-power consumption
  • Direct interface with TTL levels
  • Inputs accept voltages up to 5.5 V
  • Flow-through pin-out architecture
  • Complies with JEDEC standard JESD8-B/JESD36
  • ESD protection:
    • HBM EIA/JESD22-A114-B exceeds 2000 V
    • MM EIA/JESD22-A115-A exceeds 200 V.
  • Specified from -40 Cel to +85Cel and from -40 Cel to +125 Cel.
