18-BIT REGISTERED BUS TRANSCEIVER
WITH 3-STATE OUTPUTS
SCES058H – NOVEMBER 1995 – REVISED SEPTEMBER 2004
Member of the Texas Instruments Widebus
Family
EPIC (Enhanced-Performance Implanted
CMOS) Submicron Process
B-Port Outputs Have Equivalent 26-
Series
Resistors, So No External Resistors Are
Required
ESD Protection Exceeds 2000 V Per
MIL-STD-883, Method 3015; Exceeds 200 V
Using Machine Model (C = 200 pF, R = 0)
Latch-Up Performance Exceeds 250 mA Per
JESD 17
Bus Hold on Data Inputs Eliminates the Need
for External Pullup/Pulldown Resistors
Package Option Includes Plastic 300-mil
Shrink Small-Outline (DL) and Thin Shrink
Small-Outline (DGG) Packages
NOTE: For tape-and-reel order entry, the DGGR package is
abbreviated to GR.
This 18-bit universal bus transceiver is designed for
1.65-V to 3.6-V VCC operation.
Data
flow
in
each
direction
is
controlled
by
output-enable (OEAB and OEBA) and clock-enable
(CLKENAB and CLKENBA) inputs. For the A-to-B
data flow, the data flows through a single register.
The B-to-A data can flow through a four-stage
pipeline register path, or through a single register
path, depending on the state of the select (SEL)
input.
appropriate CLKEN inputs are low. The A-to-B data transfer is synchronized to the CLKAB input, and B-to-A data
transfer is synchronized with the CLK1BA and CLK2BA inputs.
The B outputs, which are designed to sink up to 12 mA, include equivalent 26-
resistors to reduce overshoot
and undershoot.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH162525 is characterized for operation from –40
°C to 85°C.
