74ABT2240
Octal inverting buffer with 30 Ω series termination resistors;
3-state
Rev. 04 — 17 January 2005
Product data sheet
1. General description
The 74ABT2240 high performance BiCMOS device combines low static and dynamic
power dissipation with high speed.
The 74ABT2240 device is an octal inverting buffer that is ideal for driving bus lines. The
device features two output enable inputs (1OE and 2OE), each controlling four of the
3-state outputs.
The 74ABT2240 is designed with 30 Ω series resistance in both the HIGH and LOW
states of the output. This design reduces line noise in applications such as memory
address drivers, clock drivers and bus receivers/transmitters.
The 74ABT2240 is the same as the 74ABT240. The part number has been changed to
reflect industry standards.
2. Features
■ Octal bus interface
■ 3-state buffers
■ Live insertion and extraction permitted
■ Outputs include series resistance of 30 Ω, making external termination resistors
unnecessary
■ Output capability: +12 mA and −32 mA
■ Latch-up protection:
◆ JESD78: exceeds 500 mA
■ ESD protection:
◆ MIL STD 883 method 3015: exceeds 2000 V
◆ Machine model: exceeds 200 V
■ Power-up 3-state
■ Same part as 74ABT240

[1] 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.
[2] Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
[3] This is the increase in supply current for each input at 3.4 V.

Modifications:
• The format of this data sheet has been redesigned to comply with the new presentation and
information standard of Philips Semiconductors.
• Section 2 “Features”: modified ‘JEDEC Std. 17’ into ‘JESD78’.
• Table 8 “Dynamic characteristics”: changed min value of tPZL from 4.2 ns into 3.5 ns for both conditions
VCC = 5.0 V at Tamb = 25 °C and VCC = 5.0 V ± 0.5 V at Tamb = −40 °C to +85 °C.

16. Definitions
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
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.
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
