描述 Description

These quad differential drivers are TTL input-topseudo-ECL-differential-output used for digital data transmission over balanced transmission lines. All devices in this family have four drivers with a single enable control in a common package.

特性 Features

■ Pin-equivalent to the general-trade 26LS31 device, with improved speed, reduced power consumption, and significantly lower levels of EMI

■ Four line drivers per package

■ Meets ESDI standards

■ 2.0 ns maximum propagation delay

■ Single 5.0 V ± 10 supply

■ Operating temperature range: ?40 °C to +125 °C (wider than the 41 Series)

■ 400 Mbits/s maximum data rate

■ Logic to convert TTL input logic levels to differential, pseudo-ECL output logic levels

■ No line loading when VCC = 0 (BDG1A, BDP1A only)

■ High output driver for 50 ? loads

■ <0.2 ns output skew (typical)

■ On-chip 220 ? loads available

■ Third-state outputs available

■ Surge-protection to ±60 V for 10 ms available (BPNGA, BPNPA, BPPGA)

■ Available in four package types

■ ESD performance better than the 41 Series

■ Lower power requirement than the 41 Series
