Fairchild 74VCX162245 Data Handbook
Summary
This advanced 16-bit bidirectional transceiver is engineered for robust, low voltage data communication applications operating between 1.65V and 3.6V. Featuring non-inverting buffers, three-state outputs, and integrated 26Ω series resistors on one port, this device significantly reduces noise in bus architectures. The accompanying manual provides comprehensive technical details, including electrical characteristics, timing diagrams, and performance specifications. It is the ideal choice for engineers developing high-speed data buses, memory address drivers, or sophisticated transceivers requiring low power consumption and reliable signal integrity.

74VCX162245 Low Voltage 16-Bit Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs and 26Ω Series Resistors in A Port Outputs General Description Features The VCX162245 contains sixteen non-inverting bidirec- 1.65V–3.6V VCC supply operation tional buffers with 3-STATE outputs and is intended for bus
3.6V tolerant inputs and outputs
oriented applications. The device is byte controlled. Each
26Ω series resistors in A port outputs
byte has separate 3-STATE control inputs which can be
shorted together for full 16-bit operation. The T/R inputs t PD (B to A)
determine the direction of data flow through the device.
3.4 ns max for 3.0V to 3.6V VCC
The OE inputs disable both the A and B ports by placing

them in a high impedance state.
The 74VCX162245 is designed for low voltage (1.65V to 8.6 ns max for 1.65V to 1.95V VCC
3.6V) VCC applications with I/O compatibility up to 3.6V. Power-down high impedance inputs and outputs The 74VCX162245 is also designed with 26Ω series resis-
