74VCX16601
Low Voltage 18-Bit Universal Bus Transceivers with 3.6V
Tolerant Inputs and Outputs
General Description
Features
The VCX16601 is an 18-bit universal bus transceiver which
combines D-type latches and D-type flip-flops to allow data
flow in transparent, latched, and clocked modes.
Data flow in each direction is controlled by output-enable
(OEAB and OEBA), latch-enable (LEAB and LEBA), and
s 1.65V–3.6V VCC supply operation
s 3.6V tolerant inputs and outputs
s tPD (A to B, B to A)
2.9 ns max for 3.0V to 3.6V VCC
clock (CLKAB and CLKBA) inputs. The clock can be con-
trolled by the clock-enable (CLKENAB and CLKENBA)
inputs. For A-to-B data flow, the device operates in the
3.5 ns max for 2.3V to 2.7V VCC
7.0 ns max for 1.65V 1.95V VCC
transparent mode when LEAB is HIGH. When LEAB is s Power-down high impedance inputs and outputs
LOW, the A data is latched if CLKAB is held at a HIGH-to- s Supports live insertion/withdrawal (Note 1)
LOW logic level. If LEAB is LOW, the A bus data is stored
in the latch/flip-flop on the LOW-to-HIGH transition of
CLKAB. When OEAB is LOW, the outputs are active. When
s Static Drive (IOH/IOL)
±24 mA @ 3.0V VCC
OEAB is HIGH, the outputs are in the high-impedance
state.
Data flow for B to A is similar to that of A to B but uses
OEBA, LEBA, CLKBA and CLKENBA.
±18 mA @ 2.3V VCC
±6 mA @ 1.65V VCC
s Uses patented noise/EMI reduction circuitry
The VCX16601 is designed for low voltage (1.65V to 3.6V) s Latchup performance exceeds 300 mA
VCC applications with I/O capability up to 3.6V.

The VCX16601 is fabricated with an advanced CMOS
Human body model > 2000V
technology to achieve high speed operation while maintain-
Machine model >200V
ing low CMOS power dissipation.
Note 1: To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.
