description

These devices consist of bus-transceiver circuits, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the data bus or from the internal storage registers. Output-enable (OEAB and OEBA

) inputs are provided to control the transceiver functions. Select-control (SAB and SBA) inputs are provided to select real-time or stored data transfer. The circuitry used for select control eliminates the typical decoding glitch that occurs in a multiplexer during the transition between stored and real-time data. A low input level selects real-time data, and a high input level selects stored data. Figure 1 illustrates the four fundamental bus-management functions that can be performed with the octal bus transceivers and registers.

Data on the A or B data bus, or both, can be stored in the internal D-type flip-flops by low-to-high transitions at the appropriate clock (CLKAB or CLKBA) terminals, regardless of the select- or output-control terminals. When SAB and SBA are in the real-time transfer mode, it is 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. When all other data sources to the two sets of bus lines are at high impedance, each set of bus lines remains at its last state.

description (continued)

The -1 versions of the SN74ALS651A and SN74ALS652A are identical to the standard versions except that the recommended maximum I

OL

for the -1 versions is increased to 48 mA. There are no -1 versions of the

SN54ALS652, SN54ALS653, SN74ALS653, and SN74ALS654. The SN54ALS’ and SN54AS’ families are characterized for operation over the full military temperature range

of –55°C to 125°C. The SN74ALS’ and SN74AS’ families are characterized for operation from 0°C to 70°C.

* On products compliant to MIL-PRF-38535, this parameter is based on characterized data but is not production tested. †

For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.

‡

These parameters are measured with the internal output state of the storage register opposite that of the bus input.

LOAD CIRCUIT

FOR OPEN-COLLECTOR OUTPUTS

NOTES: A. CL includes probe and jig capacitance.

B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.

Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control. C. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, Zo = 50 Ω, tr ≤ 2 ns, tf≤ 2 ns. D. The outputs are measured one at a time with one transition per measurement.
