18-BIT UNIVERSAL BUS TRANSCEIVER
WITH 3-STATE OUTPUTS
SCES024J – JULY 1995 – REVISED OCTOBER 2004
Member of the Texas Instruments Widebus™
Family
UBT™ Transceiver Combines D-Type Latches
and D-Type Flip-Flops for Operation in
Transparent, Latched, or Clocked Modes
Operates From 1.65 V to 3.6 V
Max tpd of 3.9 ns at 3.3 V
±24-mA Output Drive at 3.3 V
Bus Hold on Data Inputs Eliminates the Need
for External Pullup/Pulldown Resistors
Latch-Up Performance Exceeds 250 mA Per
JESD 17
ESD Protection Exceeds JESD 22
- 2000-V Human-Body Model (A114-A)
- 200-V Machine Model (A115-A)
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),
latch-enable
(LEAB and LEBA), and clock (CLKAB and CLKBA)
inputs. For A-to-B data flow, the device operates in
the transparent mode when LEAB is high. When
LEAB is low, the A data is latched if CLKAB is held at
a high or low logic level. If LEAB is low, the A data is
stored
in
the
latch/flip-flop
on
the
low-to-high
transition of CLKAB. When OEAB is high, the outputs
are active. When OEAB is low, the outputs are in the
high-impedance state.
complementary (OEAB is active high, and OEBA is active low).
