Description : 16-BIT BUS TRANSCEIVERS WITH 3-STATE OUTPUTS

DESCRIPTION:
Maxwell Technologies’ 54LVTH162245 devices are 16-BIT (dual-octal) non-inverting 3-STATE TRANSCEIVERS designed for low-voltage (3.3V) VCC operation, but WITH the capability to provide a TTL interface to a 5V system environment. These devices can be used as two 8-bit TRANSCEIVERS or one 16-BIT transceiver. The devices allow data transmission from the A BUS to the B BUS or form the B BUS to the A BUS, depending on the logic level at the direction-control (DIR) input. The output enable (OE) input can be used to disable the device so that the BUSes are effectively isolated. The A-port OUTPUTS, which are designed to source or sink up to 12 mA, include equivalent 22-Ω series resistors to reduce overshoot and undershoot.

FEATURES:
• A-Port OUTPUTS have equivalent 22-Ω series resistors, so no external resistors are required
• Support mixed-mode signal operation (5V input and output voltages WITH 3.3V VCC)
• Support unregulated battery operation down to 2.7V
• Typical VOLP (output ground bounce) < 0.8V at VCC = 3.3V, TA = 25°C
• IOFF and power-up 3-STATE support hot insertion
BUS hold on data inputs eliminates the need for external pullup/pulldown resistors
• Distributed VCC and GND pin configuration minimizes highspeed switching noise
• Flow-through architecture optimizes PCB layout
• Total dose hardness:
    - > 100 krad (Si), depending upon space mission
• Package: 48 pin RAD-PAK® flat pack

Description : Octal BUS TRANSCEIVERS (non-inverted 3-STATE OUTPUTS)

Octal BUS TRANSCEIVERS (non-inverted 3-STATE OUTPUTS)

This octal BUS TRANSCEIVERS is designed for asynchronous two-way communication between data BUSes. The devices transmit data from the A BUS to the B BUS or from the B BUS to the A BUS depending upon the level at the direction control (DIR) input. The enable input (G) can be used to disable the device so that the BUSes are effectively isolated.

Description : 16-BIT BUS TRANSCEIVERS WITH 3-STATE OUTPUTS

Description
The HD74LVC16245A has sixteen two direction buffers, for the fittest at two direction BUS lines WITH three state
OUTPUTS. A direction control input, DIR. When DIR is high, data flows from the A inputs to the B OUTPUTS. When DIR is low, data flows from the B inputs to the A OUTPUTS. When enable inputs (G) is high, disables both A and B ports by placing then in a high impedance. 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
•  VCC= 2.0 V to 5.5 V
•  All inputs VIH(Max.) = 5.5 V (@VCC= 0 V to 5.5 V)
•  All OUTPUTS VOUT(Max.) = 5.5 V (@VCC= 0 V or output off state)
•  Typical VOLground bounce < 0.8 V (@VCC= 3.3 V, Ta = 25°C)
•  Typical VOHundershoot > 2.0 V (@VCC= 3.3 V, Ta = 25°C)
•  High output current ±24 mA (@VCC= 3.0 V to 5.5 V)
