DESCRIPTION:
DRIVE FEATURES:
鈥?High Output Drivers: 鹵24mA
鈥?Suitable for Heavy Loads
This 32-bit bus transceiver is built using advanced dual metal CMOS
technology. This high-speed, low power transceiver is ideal for asynchro-
nous communication between two busses (A and B). The Direction and
Output Enable controls are designed to operate the device as either four
independent 8-bit transceivers or one 32-bit transceiver. The direction
control pins (DIR) control the direction of data flow. The output enable pins
(OE) override the direction control and disable both ports. All inputs are
designed with hysteresis for improved noise margin.
The ALVCH32245 has been designed with a 鹵24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
The ALVCH32245 has 鈥渂us-hold鈥?which retains the inputs鈥?last state
whenever the input bus goes to a high impedance. This prevents floating
inputs and eliminates the need for pull-up/down resistors.
APPLICATIONS:
鈥?3.3V high speed systems
鈥?3.3V and lower voltage computing systems
