74ABTH16952
16-bit registered transceiver (3-State)
FEATURES
• Two 8-bit registered transceivers
DESCRIPTION
The 74ABT16952 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
• Live insertion/extraction permitted
• Power-up 3-State
The 74ABT16952 is a dual octal registered transceiver. Two 8-bit
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 (nCPXX) provided that the Clock
Enable (nCEXX) is Low. The data is then present at the 3-State
output buffers, but is only accessible when the Output Enable
(nOEXX) is Low. Data flow from A inputs to B outputs is the same as
for B inputs to A outputs.
• 74ABTH16952 incorporates bus-hold data inputs which eliminate
the need for external pull-up resistors to hold unused inputs
• Power-up reset
• Multiple V and GND pins minimize switching noise
CC
• Independent registers for A and B buses
• Output capability: +64mA/–32mA
Two options are available, 74ABT16952 which does not have the
bus-hold feature and 74ABTH16952 which incorporates the
bus-hold feature.
• Latch-up protection exceeds 500mA per Jedec Std 17
• ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
• Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs

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.

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. For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.
4. This parameter is valid for any V between 0V and 2.1V with a transition time of up to 10msec. From V = 2.1V to V = 5V ± 10% a

transition time of up to 100µsec is permitted.
5. Unused pins at V or GND.

6. This is the bus hold overdrive current required to force the input to the opposite logic state.

Definitions
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.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). 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.
