Overview

INTEGRATED CIRCUITS 74LVC652 Octal transceiver/register with dual enable (3-State) Product specification Supercedes data of 1993 Dec 01 IC24 Data Handbook 1998 Jul 29 Philips Semiconductors Philips Semiconductors Product specification Octal transceiver/register with dual enable (3-State) 74LVC652 *FEATURES • Wide supply voltage range of 1.
2V to 3.
6V • In accordance with JEDEC standard no.
8-1A • CMOS low power consumption • Direct interface with TTL levels • 5 Volt tolerant inputs/outputs, for interfacing with 5 Volt logic DESCRIPTION The 74LVC652 is a high performance, low-power, low-voltage Si-gate CMOS device, superior to most advanced CMOS compatible TTL families.
Inputs can be driven from either 3.
3V or 5.
0V devices.
In 3-State operation, outputs can handle 5V.
This feature allows the use of these devices as translators in a mixed 3.
3V/5V environment.
The 74LVC652 consist of 8 non-inverting bus transceiver circuits with 3-State outputs, D-type flip-flops and control circuitry arranged for multiplexed transmission of data directly from the internal registers.
Data on the ‘A’ or ‘B’ or both buses, will be stored in the internal registers, at the appropriate clock inputs (CPAB or CPBA) regardless of the select inputs (SAB and SBA) or output enable (OEAB and OEBA) control inputs.
Depending on the select inputs SAB and SBA data can directly go from input to output (real time mode) or data can be controlled by the clock (storage mode), this is when the OEn inputs this operating mode permits.
The output enable inputs OEAB and OEBA determine the operation mode of the transceiver.
When OEAB is LOW, no data transmission from An to Bn is possible and when OEBA is HIGH, there is no data transmission from Bn to An possible.
When SAB and SBA are in the real time transfer mode, it is also possible to store data without using the internal D-type flip-flops by simultaneously enabling OEAB and OEBA.
In this configuration each output reinforces its input.
