100398  
Quad Differential ECL/TTL Translating Transceiver  
with Latch  
General Description  
Features  
■ Differential ECL input/output structure  
The 100398 is a quad latched transceiver designed to con-  
vert TTL logic levels to differential F100K ECL logic levels  
and vice versa. This device was designed with the capabil-  
ity of driving a differential 25Ω ECL load with cutoff capabil-  
ity, and will sink a 64 mA TTL load. The 100398 is ideal for  
mixed technology applications utilizing either an ECL or  
TTL backplane.  
■ 64 mA FAST TTL outputs  
■ 25Ω differential ECL outputs with cut-off  
■ Bi-directional translation  
■ 2000V ESD protection  
■ Latched outputs  
The direction of translation is set by the direction control  
pin (DIR). The DIR pin on the 100398 accepts TTL logic  
levels. A TTL LOW on DIR sets up the ECL pins as inputs  
and TTL pins as outputs. A TTL HIGH on DIR sets up the  
TTL pins as inputs and ECL pins as outputs.  
■ 3-STATE outputs  
■ Voltage compensated operating range = −4.2V to −5.7V  
A LOW on the output enable input pin (OE) holds the ECL  
output in a cut-off state and the TTL outputs at a high  
impedance level. A HIGH on the latch enable input (LE)  
latches the data at both inputs even though only one output  
is enabled at the time. A LOW on LE makes the latch trans-  
parent.  
The cut-off state is designed to be more negative than a  
normal ECL LOW level. This allows the output emitter-fol-  
lowers to turn off when the termination supply is −2.0V, pre-  
senting a high impedance to the data bus. This high  
impedance reduces termination power and prevents loss of  
low state noise margin when several loads share the bus.  
The 100398 is designed with FAST TTL output buffers,  
featuring optimal DC drive and capable of quickly charging  
and discharging highly capacitive loads. All Inputs have  
50 kΩ pull-down resistors.
