STMicroelectronics 74VCX16244TTR Low Voltage 16-Bit Buffer/Line Driver

The 74VCX16244TTR from STMicroelectronics is a high-performance, low-voltage 16-bit buffer and line driver designed to operate at 3.3V supply level. This integrated circuit is part of the VCX family, which is known for its versatility and efficiency in a wide range of digital applications. The 74VCX16244TTR is particularly well-suited for driving bus lines or buffer memory address registers thanks to its high current output capability and low static power consumption.

With its bidirectional interface, the 74VCX16244TTR allows for greater flexibility in system design. The device features 16 non-inverting buffers with 3-state outputs, which makes it ideal for multiplexed data transmission. The 3-state outputs ensure that the device can be placed in a high-impedance mode, effectively disconnecting the output from the circuit, which is a critical feature for preventing bus contention.

The 74VCX16244TTR is designed with advanced 3.3V CMOS technology, which allows it to support 5V tolerant inputs. This capability enables the device to interface with 5V systems, making it a versatile choice for mixed-voltage applications. The device also provides guaranteed output skew, which helps maintain signal integrity, crucial in high-speed data environments.

Key features of the 74VCX16244TTR include:

• High-speed operation: t<sub>PD = 3.9 ns (max) at V<sub>CC = 3.3V
• Power-down high-impedance inputs and outputs
• ±24 mA output drive at 3.3V
• CMOS low power consumption
• ESD performance: HBM > 2000V; MM > 200V

Furthermore, the 74VCX16244TTR comes in a TSSOP48 (Thin Shrink Small Outline Package) form factor, which makes it suitable for applications where space is at a premium. The device is also fully specified for partial power-down applications using the I<sub>OFF circuitry, which prevents damaging current backflow through the device when it is powered down.

The 74VCX16244TTR is an excellent choice for designers who require a high-speed, low-power buffer/line driver that can seamlessly integrate into a variety of digital systems, from consumer electronics to industrial controls. Its robustness and compatibility with both 3.3V and 5V systems ensure that it can meet the needs of the most demanding digital applications.
