18-bit Universal Bus Transceivers with 3-state Outputs

ADE-205-181 (Z)

Preliminary

1st. Edition

December 1996

Description

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 bus data is stored in the latch flip flop on the high to

low transition of CLKAB. Output enable OEAB is active high. When OEAB is high, the B port

outputs are active. When OEAB is low, the B port 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, and CLKBA. The output enables are

complementary (OEAB is active high, and OEBA is active low). Active bus hold circuitry is provided

to hold unused or floating data inputs at a valid logic level. All outputs, which are designed to sink up

to 12 mA, include 26 Ω resistors to reduce overshoot and undershoot.

Features

•

V_CC= 2.3 V to 3.6 V

Typical V_OLground bounce < 0.8 V (@V_CC= 3.3 V, Ta = 25°C)

Typical V_OHundershoot > 2.0 V (@V_CC= 3.3 V, Ta = 25°C)

High output current ±12 mA (@V_CC= 3.0 V)

Bus hold on data inputs eliminates the need for external pullup / pulldown resistors

All outputs have equivalent 26 Ω series resistors, so no external resistors are required.
