74LVC2952A
Octal registered transceiver with 5 V tolerant inputs/outputs;
3-state
Rev. 02 — 29 June 2004
Product data sheet
1. 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.
2. 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 °C to +85 °C and from −40 °C to +125 °C.

[1] CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in V;
N = total load switching outputs;
Σ(CL × VCC2 × fo) = sum of the outputs.

fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in V;
N = total load switching outputs;
Σ(CL × VCC2 × fo) = sum of the outputs.
[5] The condition is VI = GND to VCC

17. Disclaimers
Short-form specification — The data in a short-form specification is
extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Life support — These products are not designed for use in life support
appliances, devices, or systems where malfunction of these products can
reasonably be expected to result in personal injury. Philips Semiconductors

at their own risk and agree to fully indemnify Philips Semiconductors for any
damages resulting from such application.
Limiting values definition — Limiting values given are in accordance with
the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device.
These are stress ratings only and operation of the device at these or at any
other conditions above those given in the Characteristics sections of the
specification is not implied. Exposure to limiting values for extended periods
may affect device reliability.
Right to make changes — Philips Semiconductors reserves the right to
make changes in the products - including circuits, standard cells, and/or
software - described or contained herein in order to improve design and/or
performance. When the product is in full production (status ‘Production’),
relevant changes will be communicated via a Customer Product/Process
Change Notification (CPCN). Philips Semiconductors assumes no
