The 74ALVCH16245 16-bit CMOS transceiver from STMicroelectronics features 3.6V-tolerant I/Os and offers a maximum propagation delay of 3ns, at least 24mA of drive capability, and <40?A standby current drain.

Aimed at high-performance, low-power, low-voltage applications, and intended for two-way asynchronous communication between data buses, the 74ALVCH16245 is suited to use in high-end workstations and servers, high-speed switching systems, desktop PCs, printers, modems, LAN, and other PC cards. It can also be used as a memory-chip address driver, buffer, and mux for 3.3V SDRAMs.

Manufactured using submicron CMOS silicon gates and five layers of metal wiring, the 48-pin TSSOP device operates from a 1.65V to 3.6V and interfaces with 3.6V signals. Pin-compatible with the 74-series 16245 devices, the 74ALVCH16245 features an enable input that effectively isolates a bus.

It also has an active bus-hold circuit that holds unused or undriven inputs at a valid logic state. I/Os are fitted with circuits to protect them against up to 2kV of ESD and transient voltages. Latch-up performance is >300mA.

The 74ALVCH16245 also features power-down protection on all I/Os, as well as symmetrical output impedance. Multiple low-inductance power and ground pins minimize noise and ground bounce.
