DESCRIPTION:
dual metal CMOS technology. This high-speed, low power device is
organized as two independent 8-bit D-type transceivers with 3-state D-type
registers. The controls circuitry is organized for multiplexed transmission of
data between A bus and B bus either directly or from the internal storage
registers. Each 8-bit transceiver/register features direction control (DIR),
over-riding Output Enable control (OE) and Select lines (SAB and SBA) to
select either real-time data or stored data. Separate clock inputs are
provided for A and B port registers. Data on the A or B data bus, or both,
can be stored in the internal registers by the low-to-high transitions at the
appropriate clock pins. Flow-through organization of signal pins simplifies
layout. All inputs are designed with hysteresis for improved noise margin.
the use of this device as a translator in a mixed 3.3V/5V supply system.
which will significantly reduce line noise when used with light loads. This
driver has been developed to drive ±12mA at the designated threshold
levels.
whenever the input goes to a high impedance. This prevents floating inputs
and eliminates the need for pull-up/down resistors
