Description
These quad differential drivers are TTL input-to- pseudo-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. These drivers are compatible with many receivers, including the Lucent T echnologies Microelectronics Group 41 Series receivers and transceivers. They are pin equivalent to the general-trade 26LS31, but offer increased speed, decreased power consumption, and significantly lower levels of electromagnetic inter- ference (EMI). They replace the Lucent 41 Series drivers. The BDG1A device is the generic driver in this family and requires the user to supply external resistors on the circuit board for impedance matching. The BDGLA is a low-power version of the BDG1A, reducing the power requirement by more than one half. The BDGLA features a 3-state output with a typ- ical third-state level of 0.2 V . The BDP1A is equivalent to the BDG1A but has 220 Ω termination resistors to ground on each driver output. This eliminates the need for external pull- down resistors when driving a 100 Ω impedance line. The BPNGA and BPNP A are equivalent to the BDG1A and BDP1A, respectively, except that a light- ning protection circuit has been added to the driver outputs. This circuit will absorb large transitions on the transmission lines without destroying the device. The BPPGA combines the features of the BPNGA and BPNP A. T wo of the gates have their outputs ter- minated to ground through 220 Ω resistors while the two remaining gates require external termination resistors. When the BDG1A and the BDP1A devices are pow- ered down, the output circuit appears as an open cir- cuit relative to the power supplies; hence, they will not load the transmission line. For those circuits with termination resistors, the line will remain impedance matched when the circuit is powered down. The BPNGA, BPNP A, BPPGA, and BDGLA will load the transmission line, because of the protection circuit, when the circuit is powered down. The packaging options that are available for these quad differential line drivers include a 16-pin DIP; a 16-pin, J-lead SOJ; a 16-pin, gull-wing SOIC; and a 16-pin, narrow-body, gull-wing SOIC.
