HD74ALVC166245A
16–Bit Dual–supply Bus Transceiver with 3–state Outputs
Description
REJ03D0158–0201
Rev.2.01
Apr. 12, 2005
The HD74ALVC166245A has 16 bus transceivers with three state outputs in a 48-pin package. When (DIR) is high,
data flows from the A inputs to the B outputs, and when (DIR) is low, data flows from the B inputs to the A outputs. A
and B bus are separated by making enable input (OE) high level. This 16-bit non-inverting bus transceiver uses two
separate power-supply rails.
And this product has two terminals (VCCA, VCCB), VCCA is connected with A bus side, VCCB is connected with control
input and B bus. VCCA and VCCB are isolated.
The A port is designed to track VCCA, which accepts voltages from 1.2 V to 2.7 V, and the B port is designed to track
VCCB, which operates at 1.4 V to 3.6 V. Therefore, Bidirectional broad voltage conversion is possible.
Low voltage and high-speed operation is suitable at the battery drive product (note type personal computer) and low
power consumption extends the life of a battery for long time operation.
Features
This product function as level shift transceiver that change VCCA input level to VCCB output level, VCCB
Input level to VCCA output level by providing different supply voltage to VCCA and VCCB.
VCCA = 1.2 V to 2.7 V, VCCB = 1.4 V to 3.6 V (VCCA < VCCB)
All control input VI (max) = 3.6 V (@VCCB = 0 V to 3.6 V)
All A bus side input outputs VI/O (max) = 3.6 V
(@VCCA = 0 V or output off state)
All B bus side input outputs VI/O (max) = 3.6 V
(@VCCB = 0 V or output off state)
High output current
A bus side: ±2 mA (@VCCA = 1.2 V)
±4 mA (@VCCA = 1.5±0.1 V)
±6 mA (@VCCA = 1.8±0.15 V)
B bus side: ±4 mA (@VCCB = 1.5±0.1 V)
±6 mA (@VCCB = 1.8±0.15 V)
±18 mA (@VCCB = 2.5±0.2 V)
±18mA (@VCCA = 2.5±0.2 V)
Ordering Information
±24 mA (@VCCB = 3.3±0.3 V)
