IDT74ALVCH16901
3.3V CMOS 18-BIT
UNIVERSAL BUS TRANSCEIVER
WITH PARITY GENERATORS/
CHECKERS AND BUS-HOLD
DESCRIPTION:
This 18-bit universal bus transceiver is built using advanced dual metal
CMOS technology. The ALVCH16901 is a dual 9-bit to dual 9-bit parity
transceiver with registers. The device can operate as a feed-through
transceiver or it can generate/check parity from the two 8-bit data buses in
either direction.
The ALVCH16901 features independent clock (CLKAB or CLKBA),
latch-enable (LEAB or LEBA), and dual 9-bit clock enable (
CLKENAB or
CLKENBA) inputs. It also provides parity-enable (SEL) and parity-select
(ODD/
EVEN) inputs and separate error-signal (ERRA and ERRB) outputs
for checking parity. The direction of data flow is controlled by
OEAB and
OEBA. When SELislow,theparityfunctionsareenabled. When SELishigh,
the parity functions are disabled and the device acts as an 18-bit registered
transceiver.
The ALVCH16901 has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
The ALVCH16901 has “bus-hold” which retains the inputs’ last state
whenever the input bus goes to a high impedance. This prevents floating
inputs and eliminates the need for pull-up/down resistors.
