100352中文资料Low Power 8-Bit Buffer with Cut-Off Drivers数据手册TI规格书

描述 Description

General Description
The 100352 contains an 8-bit buffer, individual inputs (Dn), outputs (Qn), and a data output enable pin (OEN). A Q out put follows its D input when the OEN pin is LOW. A HIGH on OEN holds the outputs in a cut-off state. The cut-off state is designed to be more negative than a normal ECL LOW level.
This allows the output emitter-followers to turn off when the termination supply is −2.0V, presenting a high impedance to the data bus. This high impedance reduces termination power and prevents loss of low state noise margin when several loads share the bus.
The 100352 outputs are designed to drive a doubly terminated 50Ω transmission line (25Ω load impedance). All in puts have 50 kΩ pull-down resistors.
