Texas Instruments SN54LVC138A
The SN74LVC138A devices are designed for highperformance memory-decoding or data-routing applications requiring very short propagation delay times. When employed with high-speed memories using a fast enable circuit, delay times of these decoders and the enable time of the memory usually are less than the typical access time of the memory.| Part No. | SN54LVC138A |

FEATURES
●1 Operate From 1.65 V to 3.6 V● Inputs Accept Voltages to 5.5 V
● Max tpd of 5.8 ns at 3.3 V
● Typical VOLP (Output Ground Bounce) < 0.8 V at VCC = 3.3 V, TA = 25°C
● Typical VOHV (Output VOH Undershoot) > 2 V at VCC = 3.3 V, TA = 25°C
● Latch-Up Performance Exceeds 250 mA Per JESD 17 3
DESCRIPTION
In high-performance memory systems, these decoders minimize the effects of system decoding. This means that the effective system delay introduced by the decoders is negligible. 2APPLICATIONS
