74ABT544
Octal latched transceiver with dual enable; inverting; 3-state
Rev. 03 — 20 April 2005
Product data sheet
1. General description
The 74ABT544 high-performance BiCMOS device combines low static and dynamic
power dissipation with high speed and high output drive.
The 74ABT544 octal latched transceiver contains two sets of D-type latches for temporary
storage of data flowing in either direction. Separate latch enable (LEAB and LEBA) and
output enable (OEAB and OEBA) inputs are provided for each register to permit
independent control of data transfer in either direction. The outputs are guaranteed to sink
64 mA.
The 74ABT544 contains two sets of eight D-type latches, with separate control pins for
each set. Using data flow from A to B as an example, when the A-to-B enable (EAB) input
and the A-to-B latch enable (LEAB) input are LOW, the A-to-B path is transparent.
A subsequent LOW-to-HIGH transition of the LEAB signal puts the A data into the latches
where it is stored and the B outputs no longer change with the A inputs. With EAB and
OEAB both LOW, the 3-state B output buffers are active and invert the data present at the
outputs of the A latches.
Control of data flow from B to A is similar, but using the EBA, LEBA and OEBA inputs.

For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.
[2]
This parameter is valid for any VCC between 0 V and 2.1 V, with a transition time of up to 10 ms. From VCC = 2.1 V to VCC = 5 V ± 10 %
a transition time of up to 100 µs is permitted.
[3]
Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
[4]
This is the increase in supply current for each input at 3.4 V.

17. Definitions
18. 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
customers using or selling these products for use in such applications do so
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.
Application information — Applications that are described herein for any
of these products are for illustrative purposes only. Philips Semiconductors
make no representation or warranty that such applications will be suitable for
the specified use without further testing or modification.
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
