Octal inverting buffer with 30 series termination resistors (3-State)
74ABT2240
FEATURES
· Octal bus interface · 3-State buffers · Live insertion/extraction permitted · Outputs include series resistance of 30, making external
termination resistors unnecessary
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 Enables (1OE, 2OE), each controlling four of the 3-State outputs. The 74ABT2240 is designed with 30 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 74ABT240-1. The part number has been changed to reflect industry standards.
· Output capability: +12mA/32mA · Latch-up protection exceeds 500mA per Jedec Std 17 · ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model
· Power-up 3-State · Same part as 74ABT240-1

NOTES: 1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C. 3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 1998 Jan 16 3

NOTES: 1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second. 2. This is the increase in supply current for each input at 3.4V. 3. This parameter is valid for any VCC between 0V and 2.1V, with a transition time of up to 10msec. From VCC = 2.1V to VCC = 5V ± 10% a transition time of up to 100µsec is permitted.
