Octal bus transceiver/register (3-State)
74ABT646A
The 74ABT646A transceiver/register consists of bus transceiver
circuits with 3-State outputs, D-type flip-flops, and control circuitry
arranged for multiplexed transmission of data directly from the input
bus or the internal registers. Data on the A or B bus will be clocked
into the registers as the appropriate clock pin goes High. Output
Enable (OE) and DIR pins are provided to control the transceiver
function. In the transceiver mode, data present at the high
FEATURES
• Combines 74ABT245 and 74ABT374 type functions in one device
• Independent registers for A and B buses
• Live insertion/extraction permitted
• Power-up 3-State
impedance port may be stored in either the A or B register or both.
• Power-up reset
The Select (SAB, SBA) pins determine whether data is stored or
transferred through the device in real-time. The DIR determines
which bus will receive data when the OE is active (Low). In the
isolation mode (OE = High), data from Bus A may be stored in the B
register and/or data from Bus B may be stored in the A register.
When an output function is disabled, the input function is still
enabled and may be used to store and transmit data. Only one of
the two buses, A or B, may be driven at a time. The examples on the
next page demonstrate the four fundamental bus management
functions that can be performed with the 74ABT646A.
• Multiplexed real-time and stored data
• Output capability: +64mA/–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
DESCRIPTION
The 74ABT646A high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.

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.

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

Here!
The 74ABT646A transceiver/register consists of bus transceiver circuits with 3-State outputs, D-type flip-flops, and
control circuitry arranged for multiplexed transmission of data directly from the input bus or the internal registers. Data
on the A or B bus will be clocked into the registers as the appropriate clock pin goes High. Output Enable (OE) and DIR
pins are provided to control the transceiver function. In the transceiver mode, data present at the high impedance port
may be stored in either the A or B register or both.

SoC solutions
The Select (SAB, SBA) pins determine whether data is stored or transferred through the device in real-time. The DIR
determines which bus will receive data when the OE is active (Low). In the isolation mode (OE = High), data from Bus
A may be stored in the B register and/or data from Bus B may be stored in the A register. When an output function is
disabled, the input function is still enabled and may be used to store and transmit data. Only one of the two buses, A or
B, may be driven at a time. The examples on the next page demonstrate the four fundamental bus management functions
that can be performed with the 74ABT646A.
