STMicroelectronics Intros 74ALVCH16245 Transceiver

STMicroelectronics Inc. (Geneva, Switzerland) announced the 74ALVCH16245, a low-voltage, 16-bit CMOS transceiver chip with 3.6V-tolerant inputs and outputs. The chip features a maximum propagation delay of 3ns (for Vcc = 3.0V to 3.6V), at least 24mA of drive capability (for Vcc = 3.0V), and static power consumption of 40µA or less. The 74ALVCH16245 is well-suited to use in high-end workstations and servers, high-speed switching systems, desktop PCs, printers, modems, LAN and other PC cards, and as a memory-chip address driver, buffer, and multiplexer for the latest 3.3V synchronous DRAMs.

The 74ALVCH16245 is fabricated with sub-micron CMOS silicon gates and five layers of metal wiring. It operates from a Vcc of 1.65V to 3.6V and interfaces with 3.6V signals. Pin-compatible with 74-Series 16245 devices, the 74ALVCH16245 features an enable input that effectively isolates a bus. In addition, all inputs and outputs are fitted with circuits to protect them against up to 2,000V of ESD and transient voltages. Latch-up performance exceeds 300mA. The 74ALVCH16245 also features power-down protection on all inputs and outputs, as well as symmetrical output impedance. Multiple low-inductance power and ground pins minimize noise and ground bounce.

Available now for $1.10 in quantities of 1,000 units, the 74ALVCH16245 comes in a 48-pin TSSOP package.
