Description
Pericom Semiconductor’s PI5C16245 is a 16-bit, 2-port bus switch
that is pin compatible with the 74 series 16245 16-bit transceiver.
Two enable signals (nBE) turn the switches on similar to the en-
able signals of the 16245. The bus switch creates no additional
propagation delay or additional ground bounce noise.
Features
Near-Zero propagation delay
5-ohm switches connect inputs to outputs
Direct bus connection when switches are ON
Ultra-low quiescent power (0.2 μA typical) – Ideally suited
for notebook applications
Pin compatible with 74 series16245
Industrial operating temperature: -40°C to +85°C
Packaging (Pb-free & Green):
