HD151245

Octal Bus Transceivers With 3 State Outputs

ADE-205-597 (Z)

1st. Edition

Dec. 2000

Description

The HD151245 featurs high speed operation and high drivability equivalent to the HD74LS245, which

realize ultra low power dissipation. This device consists of eight bus transceivers with three state outputs

in a 20 pin package. The device transmit data from the A bus to the B bus when the direction control (DIR)

input is at the high level,and from the B bus to the A bus when the DIR input is at the low level, the enable

input (G) can be used to disable the device so that the buses are effectively isolated. The power up/down

protection provides the outputs in high impedance state when Vcc is low regardless of enable input.

Features

•

High speed:

tpd = 10 ns typ.

High output current: I_OH= –15 mA

I_OL= 24 mA

•

TTL Compatible Input/Output

Wide operating temperature range: Ta = –40 to +85°C

High impedance state for both

Input/Output in power off condition.

Power Up/Down Protection
